The 318 NON believers

you are right but a 451 is not allowed in the class he's racing in plus a 451 was never offered from the factory. If I'm reading the book right the only V8 he could run is a 318 because the BB's weren't available in 88-90 and the 360 wasn't available in a car (truck only).

He could of used a 340/360 from any year in the SS/GT classes...just would not have been in GT/GA since the 340/360 carry a high HP factor then the 318....

in Super Stock...you are looking for an engine combo that put you in a certain class and a the top of the class as far as weight it concern....

you are looking for an underrated engine as far as the HP factor....
