Mowparman, By my calculations...it would be 484 cubic inches (assuming that your stroke hasn't changed).
Olds 455 bored .060 over, so what cu.in. is it now?
Thanks

Wouldnt it be close to 468? Thats what a 454 is...I didnt do the math though...
From my research, the bore is similar. The 455 had a 0.25" longer stroke than the 454.
Not being an Oldsmobile kind of guy, I had to look it up, std bore is 4.126" x 4.25" stroke, so .060" over 4.186" bore and 4.25" stroke would give 467.9 cu in,, looks pretty darn close to 468 to me.
Thanks Guys, I'll just call it a 468 Olds then.
