Thread: Head CC Question

Tweet

With the producation capabilities, or rather the lack of them, back when these heads were produced someplace between 62 and 68 is probably correct... The guy who said they were 62 might have had a set that had been milled once upon a time and the guy who sez 68 might have got a little carried away cleaning the combustion chamber on his heads...

Yupir! AND.... that brings up a real interesting point. If something alot of us have taken for gospel for years, could be that far off, such as the published cc volumes on a bread and butter chevy, learning to do (or doing if ya already know) a cc job is a really important step for beginners to know and understand. Alot of folk try to squeeze horsepressure out by shovin' stuff in, but I think its the lost art of building steps that give ya a tire twister.
