Re: What should I build? (engine)
the machine shop that built mine dynoed it at 424 hp with a holley 4779 (4150 series) 750 with mech. secondaries and manual choke.
if the double humps are rebuilt with ss valves and good springs etc. 400 is a good deal
what casting numbers are they? 186,041,462?? these are all good hp heads but some dont have accessory holes for (alter, air etc.)!!
love them all corvettes,camaros,chevelles!!!
