Make sure you have a water pump with a bypass hose.
Everything from your '87 will bolt to the l31 block.

Planning on the same swap and this is pretty much what I have found after a lot of research but you will probably need a new fuel pump because stock will not generate more than 14 lbs usually.
You can use an aftermarket intake and buy/build an adapter plate.
You will have to fabricate or modify your throttle cable bracket.
You will need a new tune, engines are radically different and it's never going to run right with the existing tune.
