Well I cant answer your question. Ok well I can part of it lol Yes the 3.9 is a 5.2 with 2 cyl's chopped off. Anyway I look at it this way why put money into a engine that after a couple hundred bucks be as powerful as a stock v8. I see the point of some people building up what they have because in some areas the v8s are a dime a dozen. I can get a v8 at my junk yard for 175.00 and they are insurance claims so getting info on them is easy since they have all the paper work, not like they are there cause they have a blown engine. Check your local yard and craigslist. At least with most junk yards they offer a 30 day warranty on engines and trannys.
