how easy would it be to swap a 5.7 350 to a 383 stroker

 

383 swapping depending if you want to keep the tbi you'll most likely need to retune your computer if your o2 sensors dont like the extra flow and probably bigger cam roller conversion highly recommend, and if your new crank is if you have a choice go internal balance , if not you'll need harmonic balancer and flywheel from 400cid sbc. The good 96 up heads are worth the new manifold required , there is an adapter to use TBI if wanted or needed. Will it pass emissions Very unlikely!!
