Does anyone know of an experienced Pontiac engine builder in the Wyoming or neighboring states area?  

Well, the Pontiac Grand Prix started out as a personal luxury car in the early 1960s. Back then, personal luxury meant a big coupe with a big V8 and a stylish interior, usually featuring plush bucket seats and a floor shifter. Exterior design bordered on flamboyant at times, but the Grand Prix made no apologies for its unabashed sense of American style and performance.

There are some guys in Casper that specialize in GTO parts they may know someone. I found them on the internet and have talked to them but don't have thier number anymore. Also contact WYO TECH in Laramie they may do it or recommend some local talent. Just don't turn some oil patch mechanic loss on our project. If they say you don't need a torque plate leave and look somewhere else. It's hard to find anybody that spends the time to get the vavle height right even the big boys. You maybe better off to order what you want from Bulter or some real pro like them.
