Very well written Derek. Good thoughts and questions. Royce hits some important points as usual.
I just want to add one thing with regard to Royce's idea that the early heads are sought for their small chamber. I don't think, and I don't have the resources at hand, the early heads(produced in just the first three months of new big block production, i.e., 332, 252, Edsel 361) had significantly smaller combustion chambers than did most common Ford-Edsel engines from '58 on. Notice I did say common heads. we continue to learn about all the exceptions.
The head that some seek that has the small combustion chamber is the COAE-D. This is the 58cc figure 8 style that was used on the '60HP352 & '61HP390. And then again there all kinds of varying combustion chambers like C2S; C3AE-C, etc.
A little indicator I've noticed on the very early machined combustion chamber heads is that they have a small, quarter size/approximately expansion hole-plug on the ends of the head. Just a quickie thing to spot if you wonder about which early heads you're looking at. |
