first, ithank each and every one of you who answered my ls-v questions! You all helped immensely! Unfortunately, I found out that ls-v was hot, located its original owner and returned it to him. so now im back to h-power again. this one is being rebuilt with built head, stage 2 cams, etc... bottom stock, but with types overbore pistons and shot peened rods. anyone know if us obd-1 ecu (95) will run this motor? I know i ask many questions, but you have all saved me such grief by helping me. also, how high can you really rev this beast? Thanx!!
