Some of you might already know this, but all Pontiac V-8s had the same dimensions. Hence, where a (Pontiac)350 will fit, a (Pontiac)455 will fit also. You can build a real powerhouse out of a Pontiac as any Ram Air parts (i.e. Heads, Cam, etc.)will bolt right in. SuperDutys and 455HOs were a bit different, though. I'm working on contacting a couple of guys that are running built-up Ponchos in their 67-72s, to see if they can give me a step-by-step on the swap. will post if anybody is interested.
