Shawn Genge's 1966 GTO
(In His own Words)

I am the owner of a 1966 GTO. After many conversations with engine builders and customers of S/D Performance, I chose S/D Performance to build my engine. Dave found me a period correct date coded 421 block and did his magic. The car with no testing or tuning ran a 12.69 @110 mph at 3200ft which had me excited. We are on a process on changing the cam to Hydraulic Roller to give the car a little more street manners. Every question on my engine was always answered quickly and to my satification. I will continue to use Dave and S/D performance on any more enginebuilds in the future. I have also recomemded Dave to any Pontiac owners in Western Canada. Dave, Lisa and Marcel are top shelf in my book.
