I disagree with the statement below. $5K to get a extra 70HP out of a 20+ year old engine is a awful lot of money. My conversion will be between 260-300HP, and (best I can tell at this point) will be about the same cost. When I am done, I will have a modern technology engine with higher output and better fuel economy than the PRV. More importantly, the ability to go to any junkyard or auto part store to get parts for the engine. I can guess that some may think "Yea, but your project is not done!" True, and in the end if it even works I may blow my target price.. However, I believe the documented Chevy V6 conversions have been under the $5k price point. This may have been Duke?
