Quick, what's your .450 and .600 lift numbers look like? You've got enough flow at .700 to make ~625 my my "rule of thumb" but guessing you've got in the ballpark of 565 right there...or about as much as I'd want to throw at a cast crank anyway!!
That sounds like one BadAzz Munchkin motor!!! 
S/St3040, That is VERY IMPRESSIVE power at a very low RPM from a short stroke motor, I know you're having to work the average 2500-6500 HP/Torque for the EM format. Like I said earlier with 340's the temptation is too easy for motors that love to rev to just throw the flow and cam to them and let the crank wind up tight to make HP.....so your combo is 'mucho impressivo'....I thinking you had some killer work (epoxy maybe?) in that Victor intake to bring the torque in early and use the HP up by 6500, I would think the smallish cam can only get you so much grunt in the middle without the intake pitching in....   That was the Highest Average per cube contest, wasn't it?
don't remember off hand but they were good, I shift it at 6500 and may even lower it more.

here's my combo, what do you think it makes?
360 .030 over
probe light weight flat tops, down in the hole a few.
eagle rods.
stock stroke stock crank
comp 308R street roller, [Email]262@.050/[/Email] 575lift
1.6 rockers
11.5:1 cr
indy 360-1s fully ported by Dwayne, 317+ at 700 with good low to mid numbers
indy intake/ 1050 dominator
I run it on a 50/50 mix could be street driven anywhere.
What kind of times do you wring out of it?
don't know yet, never really had a chance to run it hard when I had it in my sons chally. but it ran 11.20 @ 121 running on 2 bbls of the carb, had the back two off. this was a stock suspension street chally 3500#s. I'll do a whats it gonna run in a week or two when I finish the new challenger. but it's a total different combo. the motor is the same but changed a lot of other stuff.

I just completed assembling a stock stroke 360 .020 with KB107, has eddy magnum heads with the bowls blends and minor cleanup in the ports. Camshaft is a Engle 253/253 @.050 .613 lift with 1.6 rockers, M1 Magnum Single Plane Intake, 750 Holly DP. Compression is calculated to be 11.2 to 1. Quench is .043. Using stock rods that have the beams polished and arp wave lock bolts.
I think it going to be close to the 500 hp figure.

Emarine, that sounds like it would be right around 500, My approach is pretty close to that with my 341" except I've got bowl ported/pinch relieved E-heads, Comp HR 236/242 @.50 .520/.540 on 112 in at 107 (need to spread the torque for obvious reasons) aluminum rods and 10.2:1, I'm looking for ~460 @ maybe 6300 or so, by my calcs that should be pretty close...whatcha think? 
You could cam up some 8 to 10* go solid and turn it to 7k and be close to 500 if not more

500 HP will put a 3200 lb. car less than 10.50 @ almost 127 MPH. 3000 lbs.......about 10.20 @ over 129 MPH. 2800 lbs.......9.90s @ over 132 MPH. Just some perspective.

Ya gotta watch that kinda stuff. Waaay back when I was a high schooler, I recall a whompin' fast '66 Biscayne that had a "396" and column shifted TH400. Under the hood, only the headers looked non-stock. Stock valve covers, Edelbrock C-454 was painted orange, juice cam, big Holley, and some dual inlet Chevy air cleaner that was probably off of a 454 Chevelle- dual non-snorkle inlets similar to 1970 340, but with a lid that was the same dia. as the air filter element. It had Corvette rallye wheels with no trim rings, and L70-15 tires all around. The only hint as to the real nature of the beast was the spacers between the intake and the (orange painted) aluminum heads. With 3.42 gears, this thing would give up a big hole shot, and then go honkin' past about anything in high gear. Apparently was 550 cubes in a tall deck block.  I personally know of a 420+ inch small block that even has had the W-2 logo massaged off of the old castings and everything including the intake is painted to look stock save for the ceramic coated headers. Probably good for low tens, given the rest of the build.
