I just got off the phone with Ronnie in AZ. I ordered my belly pans and bumpers and we discussed the kind of engine I'd be putting in the Bus. I told him I'd like to stay as close to stock as possible. I plan on using the split case tranny and was thinking of rebuilding the engine that came with it (not original). He said that a 36 horse with counter weighted crank and increased compression ratio could be a nice runner. 3600 RPM all day long. The one in there now is a single port but that's all I know about it. Even though I have a "Slow Moving Vehicle" magnetic sticker for the back, the thought of only going 50mph scares me. Thoughts? Thanks!
