Yeah the spare engine we are building is a late 4 barrel model. Found a nice cam with matching lifters out of a 485 which is a little more aggressive on the exh. lobes. Engine guy is thinking SCJ head but maybe a little too extreme. Mainly want to trim a little weight, gain a few hp. and be able to set timing back to the original 8 deg. plus it's cool to play with. Maybe 1hp per cui.?
