The stock VW's were 1588cc and replacing the 85.5 pistons and cylinders with a 87mm set would up the cc to 1641. This was a common engine size used in the day to keep the weight of the cars down. Today a common VW build for the street or strip is a 90.5mm piston and replacing the 69mm stroke crank with a 78mm stroker for a 2015cc engine. A mildly built 2015 will live 100K miles and pull like a power stroke diesel. A highly modified 2015 will be a terror on the street or the strip, and is still small compared to some of the VW drag engines built today. Don Jackson

Hi Guys I race a b/mc vw in the 70-80 we ran @ 16.5 lbs cubin so a 1800 cc motor =110cub =1800lbs are best was 11.80 @ 110.56 now the ss/vx cars are @ 12.5 lbs so the good ones run in the 10.60-70 it looks like its time for me to come out and race NHRA in superstock in 2012 see you at the Race Big Roger @ Heads Up Performance
