i have a complete '93 4.3 out of a full size gmc, i pulled the intake off and there are plastic lifter keepers on it. My plan was to build this motor up and swap in the sy, then just freshen up the original to put back in when i got tired of playin at the track or when i chuck a rod out the side lol. My question is what are the differences between our stock engines and the '93 that i have and is it possible to swap them?
