I have a 97 Chevy 1500 It has the vortec 5.7L in it and I have a 93 GMC 1500 5.7 Motor in my garage that i was gonna use the block from to build a motor for my 97. I know i need to change the heads, Intake, timing chain and cover. I wanted to get a cam for it but i have read online that the pistons and cams are different in those blocks and was wondering if when looking for said cam i should look for the kit for a 97 or a 93? As well as do i need to change the pistons. This is my first engine build I wanna be sure I'm doing everything properly and build it to the best of my abilities. Also any cam recommendations would be great!
