i have a 98 trans am with a ls1 in it that is wrecked but the engine is still good so i bought a 98 z71 1500 truck and now i have a dead cylinder in the truck its at the shop getting a compression check and all that to see what is really wrong but if i have to replace the engine i was wanting to put the ls1 in the truck and was wondering if anyone has done a swap like this before and what i could keep and what i would have to change thanks alot
