The number that pops out to me is the 718 hp with a ported eddy head on pump gas. 
Big fingers and old age is a bear  I go back and read post that I had made earlier and proof read them before posting and find all kinds of spelling errors  Now to the update. I made the trip to Klamath with the motor and four different carbs to test, we made 15 pulls, tested all the carbs and another air cleaner. The magnetic pick up in the distributor died around 3:00 PM so that put a crimp on testing some what  Luckily the dyno shop had a stocker that I could use and ended up getting all the carbs tested The motor had two oil leaks, embarrasing as all heck All test where done with OR pump gas bought three weeks ago for the race in Mission, B.C. I forgot to go get fresh fuel so I ended up using what I had   The best pull was the third pull after warming the motor up and resetting the valves, had one tight one  ) I ran a six inch high by 16 inch wide K&N air cleaner on that pull using the Holley 9375 HP, it made 713 Ft. lbs at 4800 RPM and 775 HP at 6500 RPM. Next we put the Holley 9375 that has been modified and converted to annular boosters, it lost power   Best of 701 Ft. lbs at 4600 RPM and 742 HP at 6400 RPM BSFC varied from.354 to .410, AFR varioed from 12.36 to 12.92 on the worst side of the two tried a K&N Pro Flow air cleaner assembly on that carb and the other two also, it help this carb some, 712 Ft. Lbs at 4800 RPM and 750 HP at 6500 RPM Next was a regular Holley 9375 non HP with stock boosters jetted to stock specs, it made 714 Ft. Lbs at 4700 RPM and 762 HP at 6500 RPM, we where stopping all of the pulls at 6500 RPM. The next stock Holley 9375, one of them has been modified some in the past by person unknown. I did try to make all the pasages and bleed holes the same diameter on both of these carbs so the results are probally due to me not knowing what and where some of those changes where made like inside the metering blocks The last carb.(the mate for the tunnel ram motor) made 703 Ft. Lbbs. at 4700 RPM and 743 HP at 6300 and 6500 RPM. I then added a bottle of Pro Blend and got 704 Ft lbs at both 4700 and 4800 RPM and 748 HP at 6500 RPM. The last pull was to 7000 RPM and it made 708 Ft. Lbs at 4600 RPM and 753 HP at 6500 RPM and 749 HP at 7000 RPM, maybe the Pro Blend is worth something all in all I am very happy with the results, now to put it back in the car after fixing the pesky valley cover leak Carl, I'll try and bring the dyno sheets by your shop so you can see how the information is presented on the DTS dyno sheets. Man do I wish this iste had spell check Fat, fast fingers do make errors

760 hp pops into my head. Hope you get more. For a reference, 760 hp to me would produce 9.20 ET at 146 mph in a 3,000 lb package, at sea level.
"it made 714 Ft. Lbs at 4700 RPM and 762 HP at 6500 RPM,"
Hey, I'm within 2 hp 
8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

I was tired and in a hurry last night, I left the house at 5:30 AM and got home after 9;00 PM and had to unload the motor and parts in the rain so I was not focus on the details. The motor had a miss between 5400 and 5600 RPm on every pull, I switch plug wires around and ended up checking every one of them with ohm meter, nothing found Installed new plugs, Champion RC9YC like the ones that where in it, change distribuotr cap and rotor and four carbs. No positve results Are any of you guys running the Indy 400-3 inatke having or heard of that intake making a motor miss? One of the dyno guys said they had seen that on a SB Ford motor with a nice looking Chineses import single plane intake make the motor miss like mine was That motor with the six pak and all the other motors I've dyno tested have not had a miss like this  I had a similar miss in my old stocker the last year I ran the car, I couldn't fid or identify the cause, I sold the car with the miss and the new owner installed a set of spiral wound spark plug wires and that cured it  Looking back I had installed a new MSD 7 box in the car at the beginning of the year, I had used a MSD 404B the year before, and I had installed a new set of Moroso spark plug wires with stainless cores, evidently the new 7 boxes dod't like the solid core wires. My 518 motor has a set of Moroso 8MM spiral wound race wires for the new MSD boxes like the dyno uses, it is a Digital seven non programmable. I had a MSD7AL2 box and coil with me but it would have been a major wiring project to hook it up so I didn't Any suggestions on the cause of the miss

did the underside of the aircleaner lid look like it had been spattered with fuel?
for what is the good life if not doing things thoughtfully?

If you were running a distributor with magnetic pickup (MSD) and an alternator near it, the EMI could have been picked up by the Digital box. That seems like a low rpm for that, however. Turning off the alternator (remove belt, etc) is an easy test for this. Both the distributor pickup and the wire from the distributor to the ignition box can pick up the magnetic interference from the alternator.

I didn't notice it when changing carbs, if it was there it was not a lot I had to look at the center section of the Profile airt cleaner center element each time I change the carbs. so probally not
Thanks for sharing Cab! Hmmm...I wonder who would have a fresh drum of fuel, mopar big block distributors/parts, and holley tune up parts galore in little old Klamath Falls?

No alternator on this motor during testing,the shop uses a battery charger to keep the battery voltage up. I was using a 12V Mr Gasket belt drive water pump drive for dyno testing instead of a V belt Jeremaih, I thought about calling you during the day to see if you would want to come by but I didn't have your number, sorry Maybe next time. I know better to not take extra gaskets, exhaust, intakes, rocker covers and a oil pan gasket, shame on me

I was pretty close on my guess.
Naah, I figure I'm right around 730 at ~6200 with the 2D but should show good bit more torque at and below 4200, I've gotta pull a big B body with 3.54 gears....Now I Gotta find somebody to mod my intake for a dommy now... or throw an SV1 on that 337 
:) think:
...I missed by 10 but that was lost in your 'makeshift' distributor mods 
I'd also be interested in seeing what my QF 1050-AN does on one of your carb tests.
