A new iron curtain drawn across the 49th parallel
We yanked it a bunch of times well up past 7000 rmp, it nosed over hard around 7100

You know. With a single plane and the RPM you're pulling. I'm wondering if an 850 carb or bigger wouldn't net you another 5-7 horse. Maybe even 10. Did you guys try any other carbs?
I'm thinking Mike did some good work with the heads, and knew a better cam would make more power, but it's certainly a stout build, even with the dated cam profile.I just tried the 750 AED I already had, it just need one bump in jet size on the primary.....I'm building another engine right away so there was no chance in hell that I was going to even think about a different carb.....Mike who put the engine together tried for 2 months to get me buy a real modern cam for it and I refused!

Still going at 6500.
That's what the 114 LSA did for you. Drop it back to 107-108 and it will top out at 6500 but put a butt load more under the curve.
Lustle, can you figure the opening and closing for that cam off the numbers posted?

I like the 1lbs-ft/ci+ for almost the whole pull. Carrying those numbers to 6500 really helped the Hp numbers.
I'm just saying they have to be decent to carry the power that high. I have been north of 280 @ .600" on emissions heads with a 2.02" valve, so I know the possibilities when in the right hands. I'm thinking they had to be at least 240 cfm.So what, you want me to ask for the flow numbers if he has them? I mean, the OP is claiming these numbers on a 2.02 valve and I can tell you that many here would argue that the valve is too small.
So OP, do you have some flow numbers....or valve job specs....or percentage of bowl....or whatever else you got.

That's what I'm thinking. 240ish depending on the VJ.
The value job is 20 years old, Mike lapped them and installed new seals. He said the intakes are stock 340 Chrysler and the exhaust valves are some kind of after market.
The heads flowed 241@500 when I brought them to Mike, when the Dyno runs ended and I was a bit puzzled with the big numbers he admitted that he touched them up a bit more one night when he was bored!
Had a feeling!
I'm curious how well those total seal gapless rings worked for yah. I'm pulling my heads off this winter to give them a full port job. And stick a solid roller in. I've been thinking about maybe pulling the pistons and give the gapless rings a try. See if I pick up a couple extra PSI.
Unless I'm running gas ports, I use gapless tops.
I've seen them reduce blowby by 8-10 CFM. That was on a 400 Chevy and they suck at ring seal. They are in my engine now.
Woooooops....wasn't supposed to let M.O. Know I had something.
I will ask Mike a few details next time we talk, I know he mentioned something about degree he installed the cam at. He was also very addement about the gapless rings and how he wanted the block honed, claimed it would be good for 20hp.
He said I left 25hp on table by keeping the old cam but for the money I have into it it runs good.....plus he gapped the rings for a small shot of NOS
nice! looks like my HP guess was a few 100rpm too soon.. very nice peak #'s
