lt1 rotating assembly in older block

I have a spare lt1 with newer internals and sold the car for the lt1.
Can i put the 95lt1 rotating assembly in a 94 truck block. The things i have found is the balance is different due to lighter pistons. I would have to put on a different balancer to make the belt line up. I thought the lt1 is a internal/external balance oddball motor. Just wanting ideas. I am building a new truck motor and thought what the heck. Save $700 sounds good

If the block has a 1-piece rear seal the rotating assy will work fine. Yes, you will need a flexplate balanced for the LT1 rotating assy.

Is the balancer neutral balanced and the flywheel externally balanced, I want to put the balancer off my truck and build me a nice truck motor that i can put a little squeeze to. I hate to waste parts

The LT1 "balancer" is not a balancer, its a torsional damper, and it is neutral balanced. Only the flywheel or flexplate on a factory LT1 engine has a balance weight.

also the pick-ip blocks 64 tooth flexplate will work as well, th eweight on the flexplate is to compensate for the old 2 peice cranks weight that was on the cranks outside of the seal.
