One of these days mine will hopefully see the road, but my Corvan has an 80hp w/PG and 3:89 gears (92K documented on entire drivetrain but not driven since 1978.) For the flat surfaces of the streets I'd drive on here in the Los Angeles County area, is this combo acceptible or should I consider a switch? Phil McNear 62 8 door Corvan 65 Monza 110 convertible
