Thanks Jack for filling in "all" the Pontiac CIDs. Actually there were several sub-varients in the "small" journal CIDs, but that's way off topic. All "big" journals were 3.250. The 301 and 265 CID are short deck "economy" blocks and are generally ignored by the performance crowd.

Interestingly, today one can now either buy (already cut down) or adapt (by cutting down) one of the stroker cranks (big journal) into a 400CID block, which are very common and thereby achieve one of the larger displacements without paying a premium for the relatively rare big journal blocks. Pistons are also available at various pin heights and dish volumes to deal with stroke length and CR with various performance heads.

Maybe this is the way Packard would have developed had that engine stayed around into the 60s.
