Anyone using GT40P heads?
Hi , i have some GT40P heads on my 91 GT and was wondering has anyone ever dyno using GT40P heads? And what was the numbers ? Ill be using a E-303 cam and 70mmTBand 73 MM and Typhoon upper and lower and P heads with exhaust of course. Anyone have any clues what the HP this combo might make on fly or RWHP? Thanks for input.
