7.4 liter 454 block
The guy I bought my SS396 Chevelle from, Johan Gustafsson, kept the Chevrolet iron block engine that he used in the Chevelle. He also kept the aluminum heads, rods and pistons but put a new crank in it. Then he topped it off with a blower, and put it in the used Pro modified doorslammer he bought last year.

Re: 7.4 liter 454 block
The question is: How much horsepower can you make with an ordinary Chevrolet 454 4-bolt iron block ?
He cracked the block, I might add.

Re: 7.4 liter 454 block
I had a 30 over 454 with heavily worked oval port heads and a wild roller cam that dyno'd at 603 horse..that was pretty good 10 years ago. Gotta be low compared to others though.

Re: 7.4 liter 454 block
Yes Rob, that Harrell car of yours is awesome !
Are you using a factory 454 Chevrolet block, not an aftermarket one ?

Re: 7.4 liter 454 block
I had mine in a 65 Biscayne 4 speed ! Had to put a nodular iron case St-10....it was pretty cool on the street...no nitrous...built by a local legendary street racer and engine builder...I asked him for the cam card...he tore off a piece of paper on his desk and wrote down the lift and the valve adjustment...handed it to me and said "here is your cam card" guess it was his own special grind !
