Missed on this combo?
You say you never said you wanted 600 hp. But just the most out of it. Well with that cam and the heads that hughes advertises, that's 600 horse. If you're happy with 560. That's fine. Just don't say "you wanted the most out of it" when you really mean "I'll settle for what it does".
Tom is a nice guy. I don't see anyone saying he isn't. They will make more power than you have. And nobody said they should be the best thing since sliced bread. All I've said. Is they don't flow NEAR what hughes claims. And yes. They are fine to run.
I mentioned shady dells numbers. Whatever problems you have heard of them. I've always heard excellent things about them. That aside. The numbers I posted are very common ported J head numbers. I can get very similar results from half a dozen different sources. I just used shady cause it's right on their website. If you'd rather I can post numbers from somewhere else showing that your heads only flow close to ported J heads up to .500 lift. My point with this was that there obviously is still work that can be done. Specifically on the port. The SS. And spots other's have mentioned. And once again to show that your numbers are nowhere near what hughes advertised.
Nobody is saying throw out your heads. Stop overreacting. We are just trying to help you out. And yes. You paid for CNC work that doesn't do NEAR what they claim. Personally I like to get what I paid for. If you're happy. That's fine. Just don't get upset when we point out that part of the problems you've come on here to ask for help with, come from the heads.
And nobody said the engine is a slug. Except maybe you. You came on here to ask what was missing in your combo. We are trying to help you with that.
Nobody is bashing your ****. You asked if it was a missed combo. And a lot of guys, including some pro engine builders, have taken time out of their day to help. For free I might add. To try and find out what is going on and why. Just because you don't like the answer doesn't mean we are bashing your setup. You wanted our help to get the most out of it. And we are. If you don't like the answer. Then I guess don't ask the question?
If you want the knowledge and experience. It's here on the board. There's a ton of very helpful people here. Just don't take it so personal and overreact.
And we still haven't seen any cranking compression numbers. Or CC'd chambers. I honestly think your compression is another small part of the larger problem. The more you give us the more we can help.
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.
