I'm engine shopping for my RV6A under construction now. Does anyone on VAF have experience with installation of an O-320 B2A in an RV-6A? Need to know if there are interference problems with the nose gear mount or similar. Or will it fit Vans standard nose dragger mount (conical) for RV6A, without requiring modifications? This B2A engine is equipped with the vertical updraft sump and plugged hollow crankshaft. From photos, it looks like the prop governor pad is on the front bottom of the engine case.
Also, the B2A uses 3/8ths inch prop bolts/bushings. Can the bushings in the crankshaft flange be changed to 7/16th bushing/bolts, to allow use of various props (including Cato) that use the 7/16ths mounting bolts? Or does a crankshaft with a larger diameter flange have to be installed to accommodate the 7/16ths prop bolts?
