Steve Liggett transplanted a carbureted Vortec. Sent me beaucoups nice photos. Doesn't Darryl Tinnerstet have a Chevy block in his D? (www.delorean-parts.com) FWIW: You may be where I was this time last year. Coming from carbureted American blocks, was very wary of PRV (really of any fuel injection, foreign or otherwise). Now that I've stumbled across a 14,000 mile car is no way I'd pull current block prematurely. PRV isn't perfect. Certainly isn't high performance. But it does work, and appears quite reliable once back to specs. Chances are your fine new ride will have many other issues to address outside the engine compartment. If the car runs, I'd spend money on interior, suspension, fuel supply, list goes on... first. Trust me, THAT will be more expensive than you now estimate. In mean time you may find factory engine liveable. If not, engine swap can always be one of the last things you do. Bill Robertson #5939
