[quote=screamingchief]The 455 block is the same deal,drilled and tapped for 4 bolts,the other 400 block was'nt,I guess because it was a 2 bbl motor.quote]
I don't know about that. The pic of the block that I posted is drilled and tapped for 4 bolts. I pulled it out of a 69 catalina. The code on the block is YB which is the 265 HP 2 BBL package. So who knows what Pontaic's rhyme or reason was? Oh, I when I put it back together, this time I'm gonna make sure to make use of the outer bolt holes this time, but that's another topic.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
