So, running 37's on a SWB with the stock 89 6G72 is a game of patience and the luck of living in FLAT ______ Florida. I'm able to do 65-70mph on the interstate and have no problems with the big tires around town. This would be an impossible combination in any state with real terrain features. I found an 03 Endevour minivan that had blown up it's transmission, a not uncommon occurence with those vehicles from what I've researched. Got it for $300, the motor is smooth as butter. When I took the upper plenum off I was surprised at the runner size. Holy crap that hole is big! About a month ago came across a Bonneville in the salvage yard with a 3.8 that had as Eaton M90 supercharger on it. Been keeping my eyes open for one for a couple years now. First one I've found, needless to say it came home with me. So working on getting these two together. Making the manifold, will be relatively easy since I am not averse to cutting a hole in the hood for clearance. I'll put the updates on here.
