If I every sell my 1972 chrome bumperette DeTomaso Pantera, I'm going to claim 1,050 RWP! from my NA ( naturally aspirated) 357CI engine...Might as well go LARGE!!!...If I'm going to "claim" "HUGE HP"!!!

SORRY...No dyno sheet print-out.

WHAT???!!!...You don't trust me???!!!...Mark

5357. Engine Specs at the bottom

If you really want to know my specifics, I really believe I am 400+. Here' my build data, and later in the thread, I have my "calculated data" based on cam, head flow data, etc.

I'll post up a link to that later (but I am not sure you REALLY care.....)

Rocky


I know the yellow cars were fast. I was just having a hard time wrapping my head around how fast they really are. Thumbs Up!

I think that sounds about right.

You don't believe 500HP from an Iron Headed 351 Cleveland?
How about 700+HP 351C with Iron Heads and All Ford Hi Performance Parts!? AND with a Dyno Read-Out to Prove it! Built by a Well known Professional Engine Builder, and written up in a Popular Book, sold Years ago. If you want to 'keep-Up' with the Mighty, You need to do your Homework, and research all those who were successful. They knew of what they Preached, and then proved on every race track in the world.

My Boss has Personally built, No less than, 12 Champianship Winning NASCAR Race Engines. (I won't bore you with the Winning Race Harleys he's built). My point being...Do You think I Listened to His Team when I was Building My 357 Cleveland?

"A Closed Mind...Is An Empty Mind!". I say that, because most persons never 'Listen' to the 'Old Ones', and then follow 'It' to the Letter! When some of us claim to have built a 500+ 351C, In Their Garage, perhaps, instead of debating it, and 'getting the Ruler Out'; maybe you otta start asking Questions and LISTEN to what He Knows, And How He Did It!

I may sound Spiteful, I'am Not! Detractors mean Nothing to Me, they're just a waste of time and I wouldn't lower myself down to their level. NO Winner Would!

Race motor on race gas I totally believe you and doable. Pump gas street motor I've never seen one.

700HP out of 357CI for a 2 HP per CI ratio out of a naturally aspirated 92 octane pump gas engine!!!???

The Dodge Hellcat produces 707HP from 370CI aided by a state of the art rotating assembly & space age advanced materials, by induction air coolers & fuel injection and a Supercharger.

Not sure how to take all this Jack - cant tell if you are trying to be funny, being a douche, or suggesting I don't know what I'm talking about.

I have two engines, one is stroked the other is a stock bore and stroke. Both have aluminum heads, roller cams. Both have been dyno'd. The "stock" build puts out 385 at the wheels (ie north of 400) and cost about $6k to do. That is definitely "without even trying" IMHO...

With the Roller Cam it would be pushing 640+ HP.
Hydraulic or Solid, Does NOT Matter. That has to do with Maximum 'Obtainable' RPM, and Durability-Reliability.
With ALL engines there are trade-offs/compromises.

The terms...Maximum "Obtainable" RPM & "Durability-Reliability" are self-cancelling.

HP is gained through RPMS...the higher the RPMS the greater the HP( in concert with camshaft specifications) thus the reason that F1 engines at 2.4 ltrs produce 740HP while revving at 19,000RPMS.

The higher the RPMS the greater the wear, subsequently the shorter the "Durability-Reliability"...one cannot Have their cake & eat it too"...Mark

Or course it matters whether the camshaft is hydraulic or solid!

The Maximum "Obtainable" RPM of a 351 Cleveland could not reliably be reached using a hydraulic lifter.

As a base line, can it be agreed that a 351 Cleveland has the potential/ability to rev to 8,000 RPMS.

If we can agreed to that premise, would you then build a 8,000RPM Cleveland using hydraulic lifters?!

The answer should be a resounding unanimous "NO"!!!

Hydraulic lifters by their very design have RPM limitations not so with a solid lifter, being that a solid lifter does NOT have to rely on oil pressure to pump up the lifter...Mark

The admin. will do what he needs to, to properly place this thread. As I do not wish to hijack it further.
I have a reputation I wish to keep intact.
The above statement was aimed at Mr. 1rocketship-mark from San Francisco Bay Area.
Your some kind of rocket scientist-physicist, I Get That!
Allow Me to be more Clear. Here is what I meant for you to interpret. I'll break it down for you.
1. The 351 Cleveland, with Iron Heads(with some headwork), can be built to produce 400+ HP, using hi performance components, That work together. This is what Brent Knows, A Compliment!

2. My 357 Cleveland shows 525 HP 460 lb./ft. Torque, 'Hydraulic Flat Tappet Cam'. Granted, this is using the 'Desktop Dyno' program, Plus or Minus 4%. Not a real Dyno? This Program was produced after Inputting Averaged data from over 10,000 Dyno runs. I did all I could to reduce the Figures to the LOWEST Denominator! Take it or leave it. A Hydraulic Roller Cam puts the HP at 640, 600. Lift, duration escapes Me at this time. Yes, Again, It is a Computer Program that Shows No Gain in Horsepower using a Solid Roller Cam with equal Parameters, Excepting for the RPM Limits. This is what was meant buy "It Doesn't Matter'! Read #4.

The specs. I punched in of My 357 Included, but were Not limited to:
Huge Ports
Huge Valves
Roller Rockers 1.73:1
True Roller Timing set. Installed 'Straight-Up'.
Small 62cc Combustion Chambers. Extensive Head work, Not Limited to Polished Valve Bowls. NO Porting, ports were left UNtouched.
10.6:1 C.R.
Dual 450 Holleys on a drastically modified Weiand Tunnel Ram.
Meticulously Selected Hydraulic Flat Tappet Cam. 560 Lift, 292 adv. Dur. To keep the Compression UP.
Matsumoto Headers.
Polished Stock Cast Crank, Totally Balanced Reciprocating Assembly, Including the Con-Rod Bearings!
I'll leave it there, the rest I'll keep to myself.
3. What was meant was...using the 351C as a Base, with Iron heads, a Prominent Engine Builder was successful in Producing 700+ Horsepower, using Only Ford Hi-Performance Race parts. Probably starting with a NASCAR Manifold and a Dominator Carb. Or a Dual Quad Tunnel Ram. I don't have the Article in front of Me at this time. Yes, it was stroked, yes the heads went through a mountain of flow test work, and More.
4. Yes the Hydraulic and Solid Roller cams are different, But Not in Horsepwer. The difference is Very Little. We All know the solid Cam can hit a 'Higher Obtainable RPM', because of No Oil Pump-Up. And at the higher RPM, more HP is Produced, with the Stock Stroke. THAT is what I meant by my term 'Durability/Reliability'. BUT! in a Stroker where the RPMs are limited by the Longer 'ARM' and we know the HP and Torque are created at Lower RPM. THERE is Your 'Self-Cancellation'!
5. Being a Stone Cold 'Scorpio-Sagittarius Rising', We Hate to Be Debated and will not Tolerate Dis-Believers. Yes, it's superstition!
What's Superstitious is having a President Assassinated on My 12th Birthday, as in 'the 12 Houses'.
And 6. I grew Up in Oakland of the Bay Area, and did We do some Main Street Cruising and Backroads Racing in the Late 60's-70's! A lot of Cross-Country Driving in a '67 GTA 390 Fastback, between Oakland, Fort Riley and Chicago. Oakland to Chicago in 22 Hours Flat! I was rarely Under 90 MPH, the whole way. Super was $0.27 Cents a Gallon! I believe it was 98 Octane. Mid-Day across the Plains, I had to run the Heater at Full-Blast to keep the Engine from Over-Heating. Cooked My Feet, but saved the Engine. I Miss Those Days. Believe It or Don't!

Martin, I believe you just proved what I have been saying. If you roll your 10.6:1 Dual Quad Tunnel Ram 357 Cleveland Pantera on a chassis dyno its going to be in the 400 hp range on pump gas. Everything I see for sale is not built even close to that and they all claim to make more power.

I just don't see very many street cars putting down over 550 hp to the wheels with small inch street engines. I think I might be able to do it but I don't have a small inch motor and more cam.
310/320 duration, 0.588/0.614"lift,Compression Ratio = 10.5:1, 2.200" intake valve, 1.76" exhaust valve
Flows approximately 330CFM/225CFM , 1000+cfm carb,
Hello Marlin; I'm GLAD you are still here!

In regards to "Debating", unless the collective group is discussing an empirical absolute as an example...2+2=4 there will always exist a latitude for contrarian thought/ideologies thus is the inherent nature of "Discussion".

The attitude you exhibit & personal trait you readily acknowledge as ..."5. Being a Stone Cold 'Scorpio-Sagittarius Rising', We Hate to Be Debated and will not Tolerate Dis-Believers" ...

Does NOT bode well nor is conducive to others whom exhibit or communicate an alternative/contrarian thought or viewpoint to yours.

Very few things in life are "Set in Stone" & that time tested adage most assuredly is applicable to engine design & engine building.

You post many insightful & informative contributions to Pantera International & I have learned from those myriad of posts.

When I have an opposing viewpoint of yours or for that matter ANY other contributors, I voice my opinion, if everyone felt it necessary to..."Head for the front door" when an different opinion was voiced, then George would be talking to himself around here...& we already know that, even George argues with himself Cheers...Mark
Why does it matter if the engine is 400, 425, 450, 475 and didn't make 500 hp? What's the magic number about that?

500 is very doable in a street Cleveland BUT there are compromises that you are going to need to make in components.

450 is a much more common number and a much more comfortable and reliable engine to use.


IF you look at the specifications of the 74 GTS, "Root Beer" that Gary Hall owned and Mike Cook put into the 9's at the drag strip, that engine was nothing more than a 357 cj with A3 Motorsport heads on it.

It probably would dyno right around 450 hp.


Personally (that means in my opinion) you could hit that car with another 500 hp and not go significantly faster.

So again, personally, all these people who want to put a bigger cube engine in the car and still arrive at a 500hp something engine, probably aren't going to go any faster either, just break a lot of ZF's, suspension components and induce a lot of sheet metal cracks.

So AGAIN, what's the BFD about having to have 500hp? Does it just make you feel better that you're "packin' "? Cool

1. My name is Not Martin! I'am going to go ahead and assume, after ALL THIS, you mis-read My Name and your NOT Playing with Me.
2. I was Specific in My Very First Posting! 357C 525 Horsepower AT THE FLYWHEEL! Minus 100 HP Lost through the ZF equates to 425 HP at the Rear Wheels. Is That More Inline with Your Thinking?

Now! I've said My piece, I'am Done with this Thread, I'am Moving On with-in this Forum.

My BS meter just went OFF THE CHART!!!

There is NO WAY that 450HP propels a Pantera into the "9" second time in the 1/4 mile!!!!

Here is the list of the TOP 10 FASTEST production legal street cars.

http://jalopnik.com/5940509/th...gal-cars-in-america/

Take NOTICE that it takes 1,000 HORSEPOWER to get a car into the "9" second bracket!!!

"9" seconds with 450HP as Doug claims???!!!... NO WAY!!!

George needs to institute a drug testing policy PRIOR to some members posting.

A member from the state of New York is FIRST in line!!! Sympathy

NOW to go recalibrate my BS meter!!!...Mark

This as I recall was about 1990 or so. It was a little before cell phone videos. At least I never saw a video of it. Actually a little before cell phones with cameras too?

Gary DID put a picture of the car at the line in his 92-93 Catalog, with the tires off of the ground.

357, A3 heads. single Holley. Cam I couldn't tell you. A little before everyone had dynos apps in their cell phones too.

The only trick that I know of was they put a 5.38:1 ring and pinion in the car.

Mike said, "I drove it like I was trying to blow it up". Gary said he thought it would dyno at about 450 or so.

This picture says it was 10.04 but I was told they got it down to 9 something.

Ooops, it's the "Burgandy Express", not "Root Beer". Long time ago already. Wink

The picture is in the 92-93 Hall Catalog. Well before strokers were on every street corner.

I'm not the one that can give you the formula. Mike Cook COULD tell you.

Mike worked for Gary and was the driver of the car.

The key in the Pantera is the gearing, that I do know. You are NOT going to do it with the stock 4.22 gears.
I DID ask Mike about the rpms and as I recall he said they were limiting the engine to 7,000rpm.
For me, that seems a stretch. If you told me 8,000rpm, then I'd believe it.
I use to own a customized Volkswagen Dune Buggy had compound reduction gears, would POP Wheelies as quickly as a fat kid eats an ice cream on a hot September afternoon.

The Wheelie was accomplished with having just 60 HP.

I DON'T even buy the 10.04 seconds at 142 MPH!!!

That NOW means "2" Dog Leg shifts!

A picture & descriptive verbiage DOES NOT equal FACT!!!

From the picture looks like a rather HOT DAY in Carlsbad, NOT the most optimum air temperature to be achieving 9 second 1/4 mile runs!

This "9" second horse has been adequately beaten to death.

In other news...I'm building a Pantera to orbit Mars, I'll take pictures & pen descriptive verbiage, THUS making it FACT!!! ...Mark

There are lots of things that I can't prove personally. In fact there are entire societies of nonbelievers. Some that come to mind are the Flat Earth Society, groups that don't believe that the "Holicost" ever happened, and the "Confederate Air Force.

Since this is a for the most part a free country and a free society. One can proclaim belief and disbelief as they choose.

Just like the glass of water which is 1/2 full, how one chooses to interpret that does indicate much about that person.

There are probably a million devices in which one can "pop wheelies", those stunt bikes that all the 12 year olds like come to mind BUT how many Panteras have you ever seen do that? Not how many do you think you saw?

Believe what you choose. Mars would seem to be a good place for you? You will like it there. Have a nice "trip".
Bosswrench might know the specs on that engine ON THAT DAY? Other than him, ask Mike Cook or Bob Byers.

That car was a real US GTS but was a "total" that Gary decided to save from the junk heap but as a result he had no intention of pussy footing the thing.

Chances are there were a selection of engines depending on what they wanted to accomplish. Certainly there were a bunch of ZF's with various gear ratios.

When I knew the car, it was just a single Holley (750 dp I think) a D2AE-CA block, stock crank and rods. Forged pistons.

A3 race heads from Garys former race car.



Considering how hard the car was run odds are something broke or got blown up?

I think there are a bunch of 3.27 ring and pinion sets that were made in "bulk" for Ford for the GT40 program.

If you look at the engine rpm's vs vehicle speeds 200 something mph becomes very doable.


CSX2287, one of the Cobra Daytonna Coupes, the one that Phil Specter wound up with, was run at Bonneville also.

Shelby got Craig Breelove to drive it.

The engine wasn't anything out of the ordinary for a race Cobra.

It all depends on how you gear these cars.


2v station wagons run pretty well at the dragstrips too, depending on how you gear them.


You only need massive amounts of horsepower for the Pro catagories like Pro Stock.

This car (Gary Hall's testbed) is written up in "Panteras for the Road", by Henry Rassmussen.

The intro says the car was run at Ontario Motor Speedway, the 1/4 mile was 139 mph in "about 10 Seconds".

According to the book - Fuel was methanol, and claimed power was about 650 HP. "The engine is basically a 351 CID Ford V8" the book says.

There's a bunch of nice pictures, and the car gets about 6 pages (and a centerfold) in the main body of the book.

The car was a 74 GTS, Chassis Number 6880.

Here's more info from the ProvaMo site...
