Anyone see what Late Model Performance did with a 427ci NA, he mentioned 15.0CR 8150rpms on C12.
They did mentioned with another intake they'd see an extra 30-50HP. This made 892HP with Frankenstein's F710 heads!
I wish someone would do a pump gas hydraulic (say 24x / 25x) roller with say peak power at like 6,500-6,700, with a manifold I can close the hood (say MSD) on my C6 to see how these 710s would do. Oh, and would not give up 50 pounds of tq from 3K-5K.
I have talked with Frankenstein about this motor as it is the closest that I have seen to my combo, the Holley hi ram was holding this motor back up top. With my combo being more cubes and a better intake, both Frankenstein and LME say it should be north of 1000hp (Flywheel) NA.

Thats been done a bunch unless you mean with THOSE exact cylinder heads. We did some NA things like you were talking about a decade ago that went 143mp NA in auto car, with a stock LS7 intake. Erik Koenig builds some pretty stout engines now days with up to 100 more cubic inches and requirements like your talking about, some make every bit of 800-850 hp
Yes looking for results with those new 710 heads. Some big numbers coming from them but the builds have been race type builds with big compression and cam. Also they had manifolds that would not fit under the hood of a C6 Corvette which is where some of the restrictions show up.

Is it the manifold in general, or the lid? I've seen decent gains from swapping the lid to something that doesn't choke down at the throat.

The only results Ive seen from those heads were obviously fake engine dyno numbers (wayyyy better than pro stock torque/cubic inch and BMEP output) and a sub 900 hp 15:1 race 427 based engine which is pretty weak in my opinion for that type of build but the guy isnt known to get it right anyway so not condemning heads. Everyone talking about them but havent seen the sauce

I disagree, numbers are not fake IMO. Ben Strader himself made 2.72HP per cubic Inch on his 350ci. So far Bamman Race Engines, Baldwin Race Engines, Thompson Motorsports, LME, EFI University, CPR and soon enough HPR is building one. They all have seen similar results. Everyone's dyno around the country must be off then.

I guess you dont understand BMEP is a relation to torque output especially when I said torque per inch. I think it was something like 1.7some ft lbs/cube in the post I saw? That doesnt happen in earths atmosphere on gasoline engine. mid 1.4s is really good, 1.5s is great and your not doing that without some real compression in it, not sure if I know of any 1.6 or better that actually backs it up. 1.7 cmon now, your not 130% VE Nascar might be 1.6/inch Prostock 1.7/inch MAYBE?
HP per inch can be swayed a little easier to pump up, since horsepower itself doesnt exist its just "how long do you hold on to your torque for". Purposely build a tiny engine and buzz it and hp/inch will be up, but not always faster

I’ve done 1.6/in. The most I’ve ever seen is the mid 1.6/in. 1.7 didn’t happen. I called that the first time I seen it.

I will be one to admit I'm no engine builder, yet planning on building one right now. I'm on here more than FB or IG mainly to see what other N/A guys like myself are doing. Just seems like there are 7 engine builders getting similar results not just 1 or 2. So I take it those 7 are posting fake numbers? Either way I only have street/track results on FED's F-Series as I've installed and seen what they have done on my customer's cars. F310s, F710s and F715s all on power adder setups. Maybe I get impressed very easily but I can't wait to my N/A build going.

How many of them are claiming 1.7/in torque? There is only one that comes to mind.
