We bought a used 64 VW in 73-74 or so. It was used by an elderly lady and when we got it 50 mph was about top end. That sucked in a 70 zone, 40 miles a day and in a week or so it would go 65 eventually it topped out around 80. We later put an 87mm big bore kit on a 1500 engine in it and went to 12 Volts. Still single port though.
About 4 years ago my mate Pete (nicknamed "Turtle" because he takes foreve to make a decision) was just about to retire, he was a phone company linesman, and was on a job out in the backroads when he spotted a 1959 Beetle parked outside a little cottage, with a "For Sale" sign on it. He stopped and knocked on the door, and a little old lady answered it, he asked how much for the VW, and she said, "Would $500 be alright?" And for the first time in his life, he said, "Yes!" right away. It was almost mint, syill had the factory vase attached to the dashboard etc, ran great, paint was bit tired, but interior was perfect. My cuz helped him rub it back and prime it, and........ that's as far as he's gone, even though he's been retired for the last 3 years. Hopeless.......
