Big Block Cylinder Heads "915 vs 906"

Duration, and lots of it. Builders having been using that trick for years to "crutch" a cylinder head that doesn't flow all that great. You should read up on it. Asking for the actual dyno sheet had nothing to do with me asking about the camshaft.

It's funny to me how you always have to get nasty, with your replies. I don't think you know as much as you think you do. I certainly wouldn't listen to much of what you have to say. Is that funny enough for you? ;)

If you met RustyRob you'd love him even in grouch mode, I do. The man is one in a million. He fits his spot in this universe perfectly. Just as you and I do.

As to the cylinder head, the poor thing won't flow much beyond 340 cfm. The exhaust is the bad part on those heads, as we refer to those 906s as the 'boat anchors'. They were working better but we tried to fix 'em some more better, oops, we lost flow.

I truly wish I'd had a smaller cam and the time to test it, but it was just a test run to see what we might expect with the same cam and heads on a 500 ci engine with more compression. To bad Comp Cams blew the 500 up on the dyno by not turning the water on to it.

Now, please, tell me you want to see the actual dyno sheet because you don't believe the 9.7:1/451 could actually do what I claim it did. I mean, it's okay to want to see the sheet for some other reason, but I want it to be you don't believe! I'm used to it.
