I have a 67 firebird convertable and wanting to swap out the 71 2barrel
350 for a 400. I want to make it a 400 clone and already have the hood and proper emblems but have no idea on where to begin with my 400 build up. I would like somebody to give me a spec sheet that i could give an engine builder and be somewhat sure of the horsepower I'm going to get. I really dont need anything completely crazy, about 375-390hp. Right now I have installed a Performer Intake, #1406 600cfm carb and HEI ignition. Can anybody point me in the right direction?- posted
