I have a 68 bird that I am planning to put a 455 Pontiac engine in. Several people that I have talked to suggest going with a Chevy engine. They say that a Pontiac engine will not hold up as long as a Chevy and cost twice as much to build. I would like to stay with the Pontiac, but I don't want to drop alot of money into it if it isn't going to last. Any info? I have a Pontiac 350 and 455, they say sell both & buy Chevy. I don't know!
