My first car was also a 1966 Bug. But it was a super V 1300cc. (I think was standard in 66)
That’s right, 1966 was the year of the 1300 motor. Mine sucked #3 exhaust valve on the freeway one rainy day, so my brother and I rebuilt it with 1600 pistons, cylinders, and heads. Still not a tire-smoker, but the car had noticeably more power.
