The 1966 VW Beetle Forum

Thanks for the info. I didn’t know the serial numbers didn’t match. I thought the engine number was so low that it had to be made very early too. F0060580 I assumed would be the 60580 engine made & my Bug was number 54077. I tried to look at Samba but couldn’t find the chart. Thanks for your help.

My bugs serial # ends in 054077. My “F” engine # ends in 060580. I’ve owned the car since 2010. The engine number doesn’t match the vehicle serial number. I believe they were made in the same month, August 1965. I want to increase the engine size to 1600 by changing the cylinder/pistons & heads....
