Re: Offenhauser intake manifolds

I am gonna make a guess here that none of you have ever built and ran a carbureted small block Mopar Super Stock engine with a modified Port-O-Sonic. For Dominator proponents; the small block Chevy "Super-Sonic" was a pretty good manifold, too. Their "Turbo-Thrust" tunnel rams work well, also. Not m...

Re: Any Way To Get This Exhaust Down To 95 Decibels Or Lower Without Destroying Good Flow?

All the testing I've been subjected to was based on distance and rpm. I bought a decibel meter to confirm I could pass the testing. I can see that rpm and throttle position are related, but question with Rick the proposition that rpm is not a factor in sound generation level. On a practical observa...

Re: Crane Fireball heads

The small block Ford versions:
Those head castings were slated for production in the late 60's on the Ford 302 H.O. which never actually got into production.
Crane bought all those castings from Ford to become their ported "Fireball" heads.
If I remember correctly, they did have round exhaust ports.

Re: Valve Spring Tester

I'm in the market for a decent valve spring tester. I don't care for digital stuff, and the cheap hydraulic ones are horribly inaccurate. A well preserved Rimac would be ideal! Any recommendations for models you guys have had good luck with? Electronic gives me the heebie-jeebies... as I can see th...

Re: Indy car engine difference…

I did some Buick Indy Engine work for General Motors through the company I was working at ... got a few cams from your dad, Mike; for some development on the valve train. If only Ongais wouldn't have hit the wall on the pace lap that year; we referred to him as the "Flyin' Hawaiian". He raced about ...

Re: How to select the right carb boosters?

If the engine's demands can easily be met with a 4150 style carb (up to around 550-600 hp) then you can either use an efficient venturi shape along with a downleg booster... or a larger venturi with an annular booster. Both can give good results. If you need more airflow than that, you either end u...

Re: Indy car engine difference…

Completely different engines. The engines are homologated, and every part must be approved by IndyCar. IndyCar controls the HP output, to keep the engines even. No team can work on their engines. Engines are sealed. After an engine is approved the manufacturer can not make any component changes, wi...

Re: How to select the right carb boosters?

Are there any rules for picking the right style carb booster? Does one style work better in certain applications than the others? Whichever one will get you the best fuel delivery curve for THAT particular carburetor venturi / throttle bore. They are all better in certain places within their own be...

Re: Open or Crate?

Somebody that knows what they're doing will show up with a 302 C or F, a 327 C or a 318 Mopar and hurt a lot of feelings. Probably the 318 because the tech people will have no idea what they're looking at. The shorter stroke has less internal friction so eats up less power in the engine so when eng...

Re: SB Chevy Edelbrock Victor Ram manifold

Howdy Folks, Looking at an SB Chevy Edelbrock Victor Ram manifold for my 327 drag engine but concerned it might be too big for my combo with an 5,000 rpm stall and a 8,000 rpm max. Edelbrock state the below "Edelbrock part #7070 Victor Ram 23-degree for Small-Block Chevy is a tunnel ram manifold ba...

Re: Open or Crate?

Gather around here there hasn't been any claims. I figure putting an emphasis on the short block which is unclaimable is where the money needs to be spent. I plan to run the 350i EQ head since it has been found to flow pretty good especially with a good 5 angle job and the 2701 is just a bit better...
