I just picked up a ls1 shortblock from a 02 camaro this will be a direct swap right I already have the prc heads and I might pick up a new cam for the ls1 hopefully ill pick up alil power going from a 5.3. You guys lemme know if this is not a direct swap

 

Damn dude, you are steady changing parts on your truck. The Ls1 should swap right in as long as you change the external parts on it (oil pan, balancer, coil packs, intake, coolant crossover, etc.)

Just noticed you said short block, so you shouldn't have to change much, just bolt your stuff on

 

I change my mind a lot lol. Thanks man
