Thanks guys, the car was originally a 400 car.its a 79 trans am, I see I didn’t mention that in the post, Believe it or not I have the build sheet that came on the window, a little tattered but legible. The trans is b.o.p. t350, with shift kit. I have to agree the gears make it a slug of the line but about 60 and up its doing the dash and them some pretty quick but I think I want a little lower gear. I have the hei distributor installed, not performance brand, but how much difference would that make on my applications. As far as cams go hydraulic or flat? I was looking into the comp cams thumper kit with lifters, springs, timing chain it’s about $500 and plan on doing myself with the help of a friend. The cam part # is CL51-600-5 does this this seem reasonable with to do as far as still running the same heads with new springs and pushrods and lifters? And realistically what kind of gains are to be had from this on a 72 455
In trying not to go over $2000, that’s including gaskets etc,
2k just in the engine, trans is good but will be looking into gears
