roye@hrewheels.com Posted October 10, 2008 Share Posted October 10, 2008 A friend of mine runs a blown/nitro 455 in his GTO, he even had a write up in hod rod a few years ago. Unfortunately the photgrapher showed up the week after he had catostrophic engine failure so all he had to show were chuncks of the block and crank layed out on the ground. Your right though, there is plenty to be had with the older Pontiac engines. The stock Ram Air heads would flow very and allow the motor to rev much quicker if you ditched the factory 30 degree valve seats for a 45 or 55 degree cut. It seems to me though that cores are pretty hard to come by, at least on this coast. When ever my friend needs blocks and other core parts he drives his flat bed (chevy truck with a Pontiac motor) back to Nebraska to find them.
