Gonna put a SBC/420 into the YJ, keeping the 231. Advance and Novak have 420 to 231 adapters but they're like $600 each. I have a somewhat trashed 4l60 to 231 adapter and think I can ghetto a spud-type connector if I can mechanically connect the two together. A 420 output side casting would likely help a bunch.Watcha building? I was kind of thinking those 39s you grabbed from up this way weren't for the YJ or APV.
Now if the APV ever shits the bed I have fantasized about dropping the body atop the Chebby frame. Now that could use 39s LOL.
That's kinda what I'm thinking. APV is all plastic/fiberglass body held together with a metal spacframe. Could lower the entire shooting match onto a real 4WD frame. And I might could take you up on that offer!If the APV ever dies I'd be 100% in to help you build one of these.....
Astro van is the best platform for a "mild" build of that type.
If you're going more than mild get a SWB fullsize van.
There's zero chance the APV actually dies though because $50 tires and 20+mpg can pay for a lot of engine and trans rebuilds.
