360-383 A-debate...max builds need not apply.

.210" That's the difference in the bore sizes. Nuff said.
wazzup with the 400's then? Smog crap choked the 383 to sub 360 levels so they had to up their game in CID. Still think that was one of the biggest pigs in stock smogger form, Pathetic! Just about every big displacement motor in the last half of the 70's was a joke. Now its the base for some screaming 451's
