    A 68 wouldn't have a 455 unless the original motor was swapped out later on. Also, I do not believe the numbers you've posted will tell us anything about what motor it is. I assume it is a V8? How many valve cover bolts? 6 bolts is a 350, 5 bolts is a 400/430/455 engine family.

    Valve cover as 4 bolts an it is not the original motor if you go whit the serial # it is an 455 an the block date code is b151 /February/15 and the 1 for 71 this is what i have found but not sure.

    I don't know what engine used a 4 bolt valve cover, but it is not a 455. 455 = 5-bolt valve cover.

    It isn't an inline 6 cyl, is it? That was the base engine in a 68 Skylark.

    David G de-modded....

    Why do you think the engine serial # indicates it is a 455? As I stated, no 4-bolt valve covers on the 400-455 engine family. They are all 5 bolt.

    You may want to try one of the Pontiac boards, as they would likely have much more Pontiac 455 expertise than you'll generally find on a Buick board. Or try posting on "The Other Bench", where some other make owners hang out.
