It was Pomona. I am familiar with the old modified compact class. If memory serves me the classes were A,B,and C modifed compact. The last time I looked IHRA still listed the classes but NHRA moved the class in with maybe supermodified. The M/C classes were factored on weight to cubic inch. 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
