Late LT1 engine swap

I've decided to put a stroked 94-95 LT1 in my 81. To anyone who has done this, What do I need to watch out for?

Do a search for LT1 swap or Tuned port swap. The main differences are LT1 must use LT1 acessories; TPI can use C3 acessories. Then LT1 has Optispark where TPI has a distributor.

Just fyi that optispark is a butt. I love the LT1, a lot. but if that optispark as much as sences moisture in my 94 it starts acting up.
