As Redbird stated everything internal and external.Put another way they are as different from each other as the BBC 454 is from them.The only things they would share would be a Rochester carb and they use the same bell housing bolt pattern(which is different from Chevrolet).

Pros - you can buy it from him fairly cheap. It's a fair bit of cubes, more than the 305 in there now eh? That'll be an easy torque addon. Wow factor of saying your car has a 455 Pontiac in it (or Olds, or Buick, whatever it may be.). 455 buick is about the same weight as an SBC.
Cons - More expensive parts than an SBC, more $$ than a BBC as well. Not quite as much selection as far as aftermarket parts, especially compared to an SBC. More of a pain to shoehorn in to the car. Weird headers, remote oil filter, torque arm can't mount on tranny easily anymore, etc. (Just a few thoughts off the top of my head, probably ways around all of them, but those are just thoughts).
Read in the Engine swap forum, I think there's a sticky on a 455 Pontiac swap.

They're all about the same as far as power. No particular huge difference.
Easier and cheaper BY FAR, to use a Chevrolet 454 in one of these cars. Get more power, cost less, easier to find parts for. Easier to make it BIGGER too.
Actually, a couple of parts DO interchange... you can use the same distributor module, rotor and cap in all of them, and the spark plugs will interchange between some. Maybe a few bolts too, like I think the intake bolts will swap. Oh, and the starter. Mustn't forget that.
Other than that, can't think of ANYTHING. I suspect that has something to do with why they don't exist any more. Why would any company in its right mind, that was attempting to make a profit by mass-producing something, make 5 versions of something that produce exactly the same result but are COMPLETELY different. Even F*rd figured that out by the mid 50s. IIRC the Lincoln motor was the last "other" one to get dropped, in about 55 or so. Not that the Chevrolet motors that they kept are any "better" or "worse", especially; at least not in ways that can't easily be fixed (like all of them's non-adjustable valve train, or those stupid "bridge" things they used for the rocker arms in Olds); they just needed to STANDARDIZE on something.

Old 455? or Olds 455? 73 or prior pont. 455 in rebuildable cond. is worth bucks on E-bay. I got 300 for a bare block unbored 10 yrs ago. Block, heads, crank, pistons, intake, Ect. sold seperatly could finance a good small block. A big block in a 3rd gen. will bo a good job of twisting it into a piece of licorice stick without a lot of $$$'s into the body and suspension to control the torque. Ask anyone that has one.
