F.A.S.T. Racing.

Maybe the mph differences are due to the rear gears.....

My $.02, if I may

I think Rob pretty much nailed it...I wouldn't be at all surprised to see that the L72 cam works better upstairs than the ZL1 cam does when running unported iron exhaust manifolds. On the other hand, the bigger ZL1 stick probably softens up the bottom enough to make the car considerably easier to launch, and when you consider the weight savings of the beercan engine, that would explain why it 60's well.

A side-by-side comparison of the 2 dyno sheets would be quite interesting.

Just some random thoughts...

Manifolds and exhaust systems being equal, maybe the 780 just works better with this type of 'restriction'.

Is there a F.A.S.T. race at E town NJ this weekend ??

[Chevy454]

No...there will probably be some cars that run in the F.A.S.T. series there, but I don't believe it's a sanctioned event...

A different group than F.A.S.T., but much the same program, with some of the same cars.

Hey John, you found me a '58 rule book yet?

[John Brown]

Ha! I haven't even found me one yet.

The guy with the dragster museum doesn't have one to copy either..... sorry.
