I just bought a 91 rs that had an engine swap to a 350. But the only down side is the flywheel and egr are bad. I was looking up both parts and well this is my first project car... is it ok to run cheaper on the egr? I found some that were around a hundred but they range all the way up to like 500... any suggestions?

 

fuel injected/ carbed?? what year is the engine that was swapped to
