My name is Tod Buttermore and I was invited to this forum by George Pence, a loyal backer of my new 351C project. For those interested, I am about 4-8 weeks away from casting a sample block or two. I intend to have a couple of samples machined and built by a reputable builder, make any alterations that may need done and then start to fill initial orders of the 20-30 anxiously waiting Cleveland fans that have borne with my efforts for the last 9 months or so. If you would like to know more I can post some more info here, or if you would like to have your name added to a list of prospective customers email me privately.

Thanks,

Tod

Are you telling me that soon we will be able to buy an all aluminum engine from Mark McKeown, that will make 600 horsepower and all you gotta do is bolt it in??? Are you serious?? Do you know what this could lead to?? Have you no sense of social resposibility??? My God man, think of the ramifications on the social fabric of our poor belegured nation. This could be the straw that breaks the camels back!! A bunch of killer Panteras running amok??? I shudder to think!!!!

An aluminum block C? I guess about $12,000.

Now, if the block is about $2900 - as posted above, I doubt you would NEED to spend another $9000 to get a complete engine - if you shop wisely and wrench yourself.

If you just write a check to MME, then $12K may be close.

Now where can I find $12K??

HINT: who needs GRP 4 tail lights? Wink
Great, Doug, Ron and Larry you prove my point. Every Pantera owner will want one. They will have two and a half times the power they were designed to handle. You guys will go out and become public menaces and Nancy Pelosi will ban Panteras as being too dangerous to allow ordicnary citizens to own. Only Police and military should be allowed to have assault Panteras. You mark my words, you hot rodders will screw it up for the rest of us.
Man those grapes are sour. :P
I think that is about $500 right there.
I don't like the idea of line honing but that's what they do. Hone everything till it fits.
Since it is always on a go, no-go basis, I'm alsways afraid of the mains being just a little to loose.
I think that I'm a wory wart.

I'm not sure you can determine whether the deck is .002-.003" until the mains are finished, but I do like that number.

I know it is a "Cleveland" but is it cut for 9.2"?

Engine builders like to perform the machining work themselves, or have their preferred machine shop do the work. They don't trust the block manufacturer to get everything as "square" as they would like it. and they're probably right. So block manufacturers leave the block partially unmachined to satisfy the engine builders, it gives the engine builder more block material to work with.
I am building a 351W SVO block. in some places in the bores there is evidence of slight casting texture. This is going to require a little more then a HONE ... cost ??? I estimate if I was doing the work ?? it may need a slight hit with a boring bar then a hone ... the deck will need to be checked if its square ?? then the main caps need to be milled and block line bored and or maybe a slight hone ... can should also be honed ... in my guestimation ?? this is time and money. Buying a block could mean 1000.00 in machining ... money well spent ....

BUT AND I SAY BUT ... Tod has been involved in the manufacturing of a few other very successful FE blocks. So expect this C block to be of high quality ..which probably reduce that 1000 figure.

I must be a really spoiled old timer. Maybe just plane lucky.
I was looking to reduce compression on my Clevelands and FE's.
I never had to aligh bore, or deck any of them.

$2900 plus the shipping and another $1200 to $1500 is a lot for an engine that doesn't need a full race prep.

What happens on the first rebore with new pistons and a new pin height? You have to do it all again?

It doesn't make sense to spend that kind of money on the block. What you are tring to do is equalize the compression stokes on each cylinder.

A production block won't even care about that until 8000rpm.

Does this block have more in it then 8000rpm?
You are into titanium everything with that you know?

That's the territory where the NASCAR "hot shots" put a Hank the Crank recip assembly in the LeManns Pantera and it blew up because the welds couldn't hold the Mallory metal in the crank at that rpms.

I wouldn't trust anyone with a NASCAR background. They can't even make a bobsled go fast without blowing up.
Doug,

This is by no means intended to debate you. BUT !

Any new Amunium Block for 2900.00 with Ductile Iron sleeves and the heritage that this block has ( GENESIS, POND and 460 TRICKFLOW ) my guess and hope is it will need minimual machining less then 1000 ..but when I build a motor costing 2900 for a block totaling 12k complete I have my engine builder check everything.

MME just built CL's motor with low compression and 700hp ... not full race prep ...but close.

On the first rebore the block has already been squared up ..but I would check it again. Remember years ago .. the drag racers used to use a new block in the tow vehicle to season it prior to machining it for race prep ..thats why I would check is again.

It brand new block I would spend the money for this block for high HP other wise purchase a 1500 SVO block for the street ..NO? At this price I dont think your buying it to compare to a production block .... I think this block is for excess of 8000 rpm ..the only man who can answer that is TOD.

Titanium ?? I;m into that now on the motor I;m building anyway.


" welds couldn't hold the Mallory metal in the crank at that rpms." ..... sorry bro but I;m a certified welder in Stick and Tig and that dont sound right ..

NASCAR is another story and a subject for another day .. you got big money, big sponsors, a lot of fans, hot shot drivers,

Ron

I will say one thing. I think $2900 for an aluminum block is a really good deal, and very tempting for me.

You are right. If you are going to "invest" in a real high performance engine, you have to spend what is necessary to give it the best odds of lasting.

I suppose that there is sufficient technology to make these blocks good investments. That is as long as you don't switch over to a Chevy.
These new blocks seem like a good ideal to me. If you are shooting for 500 plus HP why gamble on a production block that will only probably be able to be bored (Rebuilt) once before tossed in the trash because the cylinder wall thickness is to thin.

Not only that it will save you money if the bottom end doesn't fly apart and bend rods, break your crank and crack your high dollar heads.

I might be interested in the aluminum block myself as I'm sure the weight savings in the rear of my car would help me go around the corners a little faster. But I sure like the longer stroke in the 9.5" blocks Smiler

George, my whole life I have wanted a car with an all aluminum 427. This is something I want to have very badly but I will never be able to have. You talking about it just makes it worse. I have wantitis so bad it is causing me bouts of depresion. Please don't keep rubbing it in what I can't have. It is making me bitter.
Ok sorry not to burst your bubbles, but has anyone thought (maybe I missed this topic/forum) about a World Man O'War 460 Ford "small block" aluminum block and heads??? see links below:

http://www.worldcastings.com/prods_pages/102075.htm

THIS IS A SMALL BLOCK FORD CRATE MOTOR THAT I GATHER IS PRETTY MUCH A BOLT IN MOTOR/HEAD COMBO WITH A 24 MONTH WARRANTY AND 600+ HP!!!
Dart, World Products and Ford Racing all sell WINDSOR blocks in alloy. If a 100% Windsor or a Clevor is your bag, then that's a good way to proceed.

The one difference you'll notice, with it's 9.2" deck height, the Clevo is limited to a 4.00" stroke. The Windsor is available in either 9.2" OR 9.5" decks, that extra 0.3" of deck allows the Windsor to fit a crankshaft with a longer stroke, up to 4.25".

However, when installing a non-Cleveland motor in a Pantera, you have to ask what exhaust systems are available. In this case, a 460 cubic inch CHI headed Clevor has no off the shelf exhaust systems available for installing it in a Pantera. All of the exhausts available for 9.5" deck motors are designed for Windsor style heads. Exhausts designed for Cleveland heads are designed for 9.2" deck blocks.

I hope that clears up some of the issues involved.

Yeah there may be some draw backs, but what a blast to drive, less weight (only 375 lbs) and a bunch more power.

Detom is a fool with champain dreams on a beer budget. Don't listen to him. He is just jealous because everyone else is getting cool stuff for their cars that he can't afford. Detom is just a Pantera "cool guy" wantabe. Just ignore him and he will go away.

"The mold is assembled, I am set to cast Wednesday morning. Despite some set-backs today outside of the foundry I was able to assemble a mold for the first sample casting. The molder is on vacation this week so I had to do alot of the work myself. The mold went together very well. I did spot some areas I want to increase metal thickness in, but over-all I am very pleased. One of the foundry guys watching and helping said he thought the set-up went together better than my FE mold does. Hopefully I will have the casting shaken out by tomorrow afternoon. Stay tuned.....Tod"

"We poured the first block this morning at 8:30 and shook it out this afternoon at 1:00. Not bad. Had one mis run flaw that was welded while the metal was still warm. Once it is heat treated and cleaned up I will put the old yardstick to it and see if it needs any dimensional attention. I may have to use a tape measure for more accurate readings.....Tod"
