I wouldn't try hopping up a Pontiac 350 on a dare. It's not even worth messing with unless it's 400 cu in or larger. It just cost too much, no bang for the buck. If they were such good engines, Nascar would have used them. $5.00 a gallon gas will kill them off. If you want somethiing different then by all mean build a Pontiac 350, it will never be a 400 or 455 and you will always know it.
