This is what I get.......

Since it's Pontiac, keep it that way. You'll have to change the frame mounts, exhaust and get another transmission. Not to mention little stuff like locate brackets and stuff. I have always liked those cars. The round headlight 70s models, not the Bandit cars. I wish you we closer, you could come over drink some ice tea with me while I build you a new Pontiac motor. I'd be glad to do it to meet a new friend. I HAVE a 1999 350 Chevy vortec engine with the really good 062 casting vortec heads that I am not going to use. I even have a turbo 350 short tail shaft transmission. I just got done not long ago reassembling the short block with all new rings and bearings. The heads only need assembling. Would take me 30 minutes. You could have all that for 350 bucks and I would even finish the engine for you...you'd need to buy a few things like oil pump and the like and the transmission is only a good core. It needs building.......but you'd have good chevy power. Those little vortecs are stump pullers. But if the car was mine, I'd stick with Pontiac.
