can it be done
You can buy an LT1 intake manifold for a carb and distributor from GM Performance Parts. The distributor will be a bit tight under a 4th Gen cowl, but will fit. A crab-style cap will make it easier.
One of the local guys done that to a 93, Ran a standard Cap. He had to but the cowl and it looked awful, for a street car that is. Of coase he could have done a little cosmetic work and made it look a little better
