Re: personal

Please accept my apologies for misinterpreting, George.

I do have an open mind, but I need strong evidence in a case like this!

I think the fact that no aftermarket company has made an open chamber aluminum head for the 351C is good evidence as to whether the open chamber is better than the closed chamber. Perhaps an overly simple argument, but I tend to align with this guy known as Occam..

Edit - one more thing - Chevy developed that open chamber head, but they didn't use it. The project wasn't stopped at the drawing phase. They had actual parts and the means to test them - and they didn't use them in production or racing cars. I would be very surprised if there wasn't more of a reason than lack of funding.
