ok so trying to decide what i wanna do. pull the ls1 out bore it .030 over forged internals good flowing heads custom grind cam and a magnacharger. or a lq4 with arp bolt everything. good flowing heads custom grind cam and a magnacharger. my goal is 500whp through a rpm 4l60e trans and yank 3600 stall converter

 

Save the weight go aluminum...it's easier to add power than to trim weight
