Why not just keep what ya got, leave it as is.... Then start accumulating goodies to build a good engine for the car???? Heck, lot easier to build them slowly over a period of time. Building one good engine and leaving the one in the car alone and just driving it as is for awhile will IMO save you money over the long term, and you'll end up with what you REALLY want instead of having to make a bunch of comprimises and settle for something less!!!!
