What kind of cam and engine work does it take to make that kind of horsepower from a "stock" L78. I'm not up on what is allowed in stock class racing.

This was talked about earlier HERE.

Gotta be stock lift cam, but duration/lsa/lca can all be moved around...big power from such a little change. Engine work, well it's a science unto itself! Sweating the details would be putting it mildly...

A Jerico 4 speed and a 538 ring and pinion and the addition of a 3/4 to 1" fuel line also help. The over the counter BB aluminum heads that NHRA certified was a big step to. But just remember they all cheat!

Sometime check out where the header bolts to the head. Usually there is a step out for the gasket and flange area..... well look again. Barely enough to hold the gasket flat against the head. I just love seeing those cast iron intake, flat tappet, mush lifter, Q-Jet 350/255 horse novas go 10.80 in G/S.

Last time I looked at Steve's car it had the stock fuel line!! That blew me away. He told me the holley bowls hold enough fuel that you don't need a big line.

I don't think I have seen any in the last couple years that were not at least 1/2" to 3/4". Maybe the rule book has a limit for Stock Eliminator, I am not sure. All I know is that even the small HP cars run good. There ain't NO shabs out there anymore! No easy rounds for the Stock/SuperStock guys.

Sam,There is on limit on size in stock. Most have bigger lines . That's what blew me away on Steves car.
