That's similar to the engine I had in a Deserter Dune Buggy, back in the day. I flipped the R&P on mine so I never had the oil belching issues but it was a lot of engine for stock transaxles back then. Used it mostly for Autocross and had to do a bit to the pan suspension to get it to handle, but eventually it became a terror on the track. The Northeast SCCA got too many complaints from people that got beat so they created a "Kit Car/Modified" class for it (E modified, IIRC - I think Piperato runs his Spyder in that class) so I ended up racing against myself or for FTD. Not a lot of fun after that so I sold it to a kid in Connecticut. That was around 1972.
