Is Dwayne going to provide you w/ any more dyno sheets? I'd be interested in seeing how the air/fuel curve looks w/ the QF 1050 carb after his final adjustments. Also, I'd like to know if his Mighty Demon 850 jetting changes took care of the typical "BG lean swing" through the mid-range. My Claw 825 showed that to some extent and I suspect the "fix" is in the metering block emulsion settings. Also #2, I see others saw the Dominator was definitely on the lean side through pretty much the entire RPM range, too.

Brad, i will be getting some more data once Dwayne has a chance to e-mail those sheets to me. He did mention the typical Demon lean spot and talked about messing with the IFR's but not sure if he did this on my tests. The Demon carb & manifold thrash took place the day after i left to come home.
Overall there were 31 dyno pulls with the 572 so lots of data to digest. 
I'll post them when i get them....what manifold and/or spacer combo are you interested in ?

I'd also like to see the printout of the 2D dual plane, especially interested in the "under the curve" torque.
Will do Bobby.....i'll post up all three if you like ? From what i can see the 2D liked the spacer...more spacer equalled increased power. Dwayne did comment that the 337 felt the best on the dyno in terms of responsiveness to throttle position. It performed better than he expected and declared it the clear winner for this particular build. 
On an engine with bigger heads, more compression and bigger cam the 440-2/440-3 would be the better choice. I'd imagine that the VE would drop off significantly at higher rpm with the 337 on a hotter build than mine.

The '337 intake using the MD 850 with or without the spacer will show me what I'm looking for.

Wow that 337 intake really held its own hu? it been interesting to see that intake with the adapter and Dominator. I bet the intake would have been within 8-10 hp of the Indy piece.
I plan on talking to my father-in-law about getting this intake when he upgrades to the Indy heads this winter.

Ron, What was the final compression ratio on the combo? Your cam is pretty close to what I have: .675 int. .651 ext. dur@.050 274 int. 284 ext. on a 114 lobe sep. My springs are set up 275 600 Wonder if I could get rid of the 4500 indy intake and go with the 4150 style so I can enjoy it more on the street. My car just never seems to be lean enough to run on the street with the 4500 dominator carb. We went with a 4.625 stroke,7.10 rod and a 4.4 bore. Always shifting 5800-6000 at the track Great job Guys

Those are some stout numbers.
Your gonna put your traction to the test. 
I can't wait to see it run, maybe you should bring it out to the osca events. 
Thanks Mark ! 
Already have the Caltracs & monoleafs (thanks Jim aka "Montessa"). If you can hook your 950tq/1050hp Hemi on those i should be ok 
I'd like to come down for at least one race next season. Also planning on going to the Mopar Event at Grand Bend.

Ron,I'm jealous!!!  721 ft. lbs. of torque!   AWESOME! You can now officially change the Charger's name to "Flying Black Pig"  Dwayne sure knows his stuff! I couldn't be happier with my SQ cam you guys picked out for me! Talk soon,Buddy! CONGRATS! Randy B.
Hi Randy, ya it's gonna be a blast. Need lots of torque to get the BP moving....she's no lightweight ! 
Make sure to schedule Grand Bend and Norwalk next year.

Thanks Rob !
Static comp was 10.6:1 which is safe with the large bore. Didn't want to push the pump gas envelope too hard. 
Originally the cam was going to be a 112 lsa but Dwayne decided to tighten it up to 110 to spike the midrange power with the 4100lb raceweight.
You should try a 4150 carb....i'm sure it would be much easier to dial in. That QF 1050 worked very well on mine.

Ron What air filter are you planning to use? The lack of a fresh air hood on a Charger limits you somewhat-but the looks are certainly worth the tradeoff. I would think it gets a bit cozy-even with the relatively low rise manifold... Just curious .... MB

Ron, You you have the DP Indy numbers to post yet? What gear are you running? I think I'll swap on the 337 when I make the 4 speed swap, right now I like that extra torque the dual plane makes and since I'm "cube defficient"  ..... The next time somebody builds one I'd like to offer up my Ported 2d to compare to a non-ported one, I think the plenum mods and opening up the throat passages to the runners out of the plenum are worth ~20hp, maybe even more on a high compression Mega-cube motor tha would push it to its limit. With that many cubes I've got to wonder how an SR or -1 with the same intake flow/port size and the raised exhaust runner would go? It'd be a cool comparison for the EZ/non EZ debate to see what the raised port is worth in the "real world". What's got me really curious is when Dwayne flowed my Chapman head he commented that the Exhaust port was a nice shape but comparatively small, but when he put the 2" tube on it it "really took off" (~300cfm)....but more and more evidence is coming out that maybe the exhaust isn't really that critical as once thought. (smaller/faster vs larger/slower and it's effect on "keeping" useable cylinder pressure and cam selection is a topic for another thread someday) I think Indy made a great move with the EZ because most RB B and E body cars upgrading to better heads and strokers already have headers (like Ron did), not much gain (apparently) to merit having to shell out another 700 bucks for raised port headers too!

Hi Mike, right now i've got the K&N 14x3 1.25in drop base assembly with a flo-thru top. Old School is running the same manifold/aircleaner on his 580 engine with a 1/2in spacer and it clears the factory hood on his 70 Charger.
I lowered the K-frame on mine 1in with spacers (thanks for the idea Big Squeeze) and will use the 1in open spacer. The 337 is pretty low....almost the same as the Holley Street dominator that's on the 446 currently. The raised Indy intake ports will tighten things up but it will still clear....i've measured. 
I agree...the scalloped stock hood looks best without a scoop.

No sheets yet Bobby....i know Dwayne is swamped so i'm sure he'll get around to it soon. 
I have 4.10's and 295/65 MT drag radials
You might be surprised at the tq curve on the 337 vs the DP.
