I have an 87 IROC that I would like to upgrade from a 350 to a 383 stroker. The question is, can I do so and still keep the TPI system? If so, how do I do it? I have basic knowledge of car restoration and rebuilds, but this is my first attempt on completely restoring a vehicle, so any advice would be kick ass! The engine is all original with 170,000 miles on it (I felt this is pretty decent considering it's a 19 yr old car). So I guess my next question is, should I salvage what I can from this engine, or start with all new parts? Let me know, Thanks!!
