I'm new the chevy sixes. I'm building a 292 for bracket racing and trying to choose parts. I'm going to use a Garrett Gt42 turbo,tial waste gate with a 80mm throttle body. Probably 60lb injectors. I'll use a 292 head with 1.94-1.60 valves and lump ports. My main questions are on the rods and pistons. I assume aluminum rods are needed? Any recommendations. Pistons? Thanks for any help.
