I am wanting to swap the LT 1 engine to a LS 1 enging. Does anyone know of any problems I would encounter??

As far as swaps go it should be pretty straight forward. You’ll have to transfer over all the extra OBDII equipment to keep it legal though. Unless you can across a cheap LS1 though, you’d do better to build up the LT1 that you do have from a cost/benefit standpoint.
