not to fond of the roof and the rear spoiler

Spoiler looks terrible...top is decent...better than the sunk in bumper, though. I do not care for that look, at all...

Someone said to the lister that Pontiac never made a big block? LOL, what about the 455? Duh.

that someone would be correct. this is no pontiac big block. the 455 shares the same basic block as the 350, 400, 428 and others.

Correct....even the 326 is the same outside dimensions....
I've rebuilt a 347, 389, and a 400, but haven't done a 455. Seems like the '55 was a 316 CU IN, if my memory serves me right....(?) and then there's the 421...they sure had a lot of different size engines......

Really? Is that also true of the olds built 455? or buick?

no, olds and buick had small and big blocks

Ok...enlighten me. If it was the same dimensions as a small block then how did they get the 455 CI measurement? Was it just larger heads that mad up the extra 100 cubes?

larger bore and stroke doesnt change the outside dimensions
