Just found out a lot more about the VW buggy. Turns out drivetrain are from a 1963 Bug. Which means 1200cc engine ~36-40hp and swing axle transaxle and not cv axle. Reading up on the VW1200 and seeing what's available to make it strong. Hopefully I won't regret my decision, was hoping it was at least a 1600cc engine with a CV transaxle. Should be a fun project hopefully. It is also, at least in stock configuration a 6 volt system. Volkswagen didn't switch to 12 volt until 1967.
