I'm new to this forum, I have owned 3 GTOs. '65, '66 and '69 but that was "back in the day" (early/mid '70s). I don't own one currently. I've been thinking of buying another '65 GTO just for fun. Can anyone tell me the deck height of a Pontiac engine? Crank centerline to head mating surface. Thanks, Kenby Ken Danielson - Pontiac GTO Forum
