holley street dominator

Here are some comparison figures Dan Jones posted on another forum. I don't know if your Street Dominator is included, but I know the Holley Strip Dominator is very highly thought of and sought after.

While the Strip Dominator is mentioned/evaluated in the linked post, the Street Dominator is not. The Strip Dominator and Street Dominator are two completely different intake manifolds, the performance of one cannot be assumed to apply to the other.

I know as George mentioned that the Strip" version is highly coveted & BIG $$$$$, when you can find one!...Mark

FYI,

After I machined the pad flat,

The individual runners are MASSIVE!...Thanks for posting the pictures Sick Cat.

Are those Yella Terra roller rockers?...Mark

I've done similar trimming to my Strip dommy. there's a few more bits you can nip off there too.

Going to polish her up too?

Hey Sick Cat - What brand and part number are your beehive springs? Also, what are your cam specs? Just curious...

When I rebuilt my engine I went with premium Pacaloy Beehive Springs (Lunati part number) and had one break within the first 1000 miles. The springs were supposed to be good for cams with .600" of lift (maybe more, I don't recall the spec), but several of the springs were out of spec (shame on me for trusting the mfgr spec and not measuring each spring) resulting in a coil bind situation. And the downside of beehive springs is that if one breaks, there's on secondary spring or damper to keep the valve from dropping into the cylinder.

So much for those Premium beehive springs - I now have tried and true dual valve springs.

We now return to your regularly scheduled Street Dominator discussion...

Here is most of the info on the engine,

Mark the rockers are Comp Cam.
Garth the springs are Isky, last page.
sorry to here that did not work out on the spring, here alot of good things about them.
Horace; how did it work out with your intake,
Mark

I am running a similar intake and the key to their performance is a 1" spacer, Wilson is the best.This intake gives you a lot of racing performance as it is a single plane type. The indication is it is designed for a Edelbrock carb.The cam you have will really pour it on , if you have the new heads ported and flowed + a very good set of headers.

Hi Mark

No further on with the intake, its still sitting here and not sure whether to keep it or sell it on.

Not been able to establish so far if the "street" dominator is any good for performance. From the responses so far the "strip" dominator seems to be the better one to have.

However came across an e bay listing recently for the rare 71/72/73 Street Dominator saying it the one to have but giving no specific reasons why, they do want nearly $400 which is interesting:

No distinguishing marks on mine to state if its the same as the one listed other than it looks very similar. It was fitted to my 74 Pantera. Anybody any ideas as to why the 71/72/73 would be more desirable

Finally last one

The street dominator is a small runner/small plenum single plane manifold, designed in an era (mid to late 1970s) when such manifolds were inordinately popular. The marketing concerns were emissions compliance and fuel economy. Engines of that era had very low compression and were fitted with tail pipe emissions equipment that hampered drivability and performance. They were significantly down in horsepower AND had terrible fuel economy as well. People were buying manifolds like this hoping to add pep to their car's performance (small runners), while at the same time improving fuel economy. This sort of manifold was never popular amongst the people I associated with.

Its a small port (2V) manifold that can be mated to large port (4V) heads due to the large flanges that surround the runners where they mate with the heads. The carburetor mounting pad design made the manifold compatible with the wide range of 4 bbl carburetors that were available when the manifold was new. It also has provision for EGR. The small cross-section of the runners should make it obvious the manifold is tuned for lower rpm, its a bit "out of step" with the 4V cylinder heads. The manifold is very similar to the Edelbrock Torker, but with smaller runners.

Mated with a "smallish" carburetor (650 cfm) the street dominator will get the job done as a street manifold for low and mid-rpm. Whether or not to keep it or trade it for something else depends upon what your goals are for your Pantera's engine. It would not be my personal choice or my recommendation, but that doesn't mean it can't provide satisfying performance in the proper application.

Hello Horace and all,
Hope I am not being confusing on this as the engine with the Strip Dominator will be interesting and probably a hand full, my stock engine that was in the Pantera when I bought it was no slotch, Very driveable around town and on a fresh set of plugs would get 17mpg, I had taken the car to a GPS 175mph across the desert, and ran the back woods of N San Diego county on the windy roads and it would climb on some very renown road cars, I own and have raced a few say 2006 Corvette's and they did not, and do not compare on straight line acceleration 55 to 140mph.
I think the Pantera I owed was pulled out of Arizona by Hall Pantera, fitted with braces, brakes, Headers, and Edelbrock # 2665 Ford 351C 4V Performer Aluminum Intake Manifold, 650cfm mechanical Demon carb that I love,2 1/2" pipes to the Ansa that are gutted and ceramic coated.
Here's the Intake:



.
The gearing on your Trans matters too,

I'm with George on the street intake, looks like it would be OK on a build that needs smog, or a truck but I would say if you want to squeeze some potential out of the car I personally would step it up to another manifold.
Mark

Thanks George/Mark

Will take your advice and pass on this intake on the new engine build.

I had the same Edelbrock performer as yours on my last Pantera though it was the 2v version as I had the Aussie 2v quench heads fitted at the time. It had superb performance right across the range so it looks like I will be buying the same again.
