Jack Ferris's 1969 GTO
(In His own Words)

I race in the higher altitude in Salt Lake City Utah. My car weighs 3200 #'s and runs in the very low 10's. Dave did the heads even after another Pontiac porter did them and found much better flow #'s than before. I send all my Pontiac customers to Dave for the head work and all are very pleased.
