New To FTE, Need help with #'s
The c9 460 would be good one to find. Those motors have much thicker cylinder walls for running big cubic inches. I have been told you can bore them out like 140 over and not have a heat problem. Never done that though, just heard. The heads are better too. They're not as smogged as the 70's heads. The D3 heads are still good, Ford hadn't really cracked down on smog yet.

All 385 blocks from '68-78 are, with the exception of two that have thicker main bearing webs (DOVE-AA/DIVE-AA, the same casting with varying deck heights from '68-70. After '70, all are 10.322".
Heads are basically the same with the exception of '72, which had open chambers, and PI and CJ with larger ports/valves. '68-71 have smaller chambers with rail rockers, '72 up (PI excepted) have pedestal rockers and the intake valve was raised .100. All non-PI/CJ have very restricted exhaust ports, but will port out to about the same flow. All 385 heads have the exhaust port smog bump. The 385 was Ford's first engine built for emissions reduction.
