I really need help. I'm trying to build a 454 engine for my 79 Camaro. The crank in the 454 is bad so i have to replace it but wanted to add a better cam and things like that while i had it apart. I've never built a engine before so all this is new to me. Any suggestions would be really helpful. i'm trying to keep it on the low end on money but will do something if its going to make a big impact. I know right now i want to replace crank, cam, lifter rods, valve's and rocker arms and maybe pistons. Engine isn't going to be bored either Casting number is 361959 and VIN T0629TST. I'm have 781 heads for it but valves need replaced. Again any help cause i'm lost.
