Missed on this combo?

I did post that I cc'd the chambers myself. 68cc. All of them. I also mentioned that I do run a 950HP. Took it right off of my in-car engine. It's been a workhorse for me. For some reason, I could not get cranking compression numbers. Tried jumping an old starter ........just didn't have enough time before I had to pull the heads. All I know is the formula says 11.4 to 1. Should have checked it on the dyno but didnt.

All I read was the short side was murdered and could not be fixed, without a million dollars and hundreds of hours. And someone screamed something about MEGA reversion. All that, in my mind, said scrap 'em.

In all the posts on the whole thread, it's the only time I took anything personal. I never do..Maybe it was the delivery of a couple posts. Maybe I'm a little pissed at mysef, too. I believed Hughes.

So now I think I have 2 choices.

Put an Airgap on with a 1 inch spacer. Get a cam ground that will take advantage of the intake and the crappy heads and hope I can get decent numbers and it won't fall on its face after 6000 RPM. I don't really know what kind of power an Airgap can make.
I DID run one on a 485 horse motor that was a monster until it fell flat at 6100. If I thought the AirGap with the right cam could make 560 on this thing with a WAY better torque curve, I'd do it in a minute.

Or.....Stick with my Super Victor and as above, try to find a cam that will help with the reversion and low mid lift flow. No underhood room for the SV and a spacer.

I already decided that cam has to go.

I don't fall over and slobber over the AG like everyone else.

Like I said, I would have flowed your heads backwards and at some different pressures to see what really is happening. Who knows....the valve job may suck (I'd bet it does) and a little fluff and buff on the short turns may have done the trick.

I have said it many times, and I'll say it again, just flowing at one test pressure is only what to do if you are comparing something quickly, like a mid lift number or what the head is doing at max lift, or just to compare things overall. It's just too vague at one test pressure to get a better picture of what's happening.

I never back cut a valve, unless there is a specific reason I want low lift flow. It induces reversion. Your valves are back cut.

I don't think you have junk. I don't even think the intake is junk. The complaint I heard was the runners are too big. On a correctly done 400 inch small block, it's hard to get the runner too big. It's hard to get the runner too big on 340 inches, so I'm not buying that.

I'd call more than one cam company and MAKE them convince you why what they want is what is correct. Like I said, I called one cam company and he said my head was up my ***. But, when questioned he had a hard time convincing me. You don't have enough intake duration (or you have too much exhaust duration) and your LSA is too wide for your induction system and the mid numbers are low.
