Your evaluation of things is grossly oversimplified.
Phil said a stock shortblock setup is 1.4hp per cube, seems reasonable he was refering to ported GM castings, GM intake setup.
Rick's car is a professionally built engine that can take more rpm(very important) with ported aftermarket castings, converted single plane intake, and a solid roller. All of those things are of critical importance to these results.

396cid, hand ported AFR 227's, ported vic-E, 246/254 .613/.590 112lsa HR.
700r4, 4000+ stall, 12 bolt.
Hard to guess on power due to unusual dyno numbers....nut I'll give you a little history.
With ported LT1 heads and a 222/228 .544/.538 cam it made 422hp/447TQ through a T56/ ten bolt....swapped in the auto...it ran 11.6 @ 116-117...swapped in the 246/254 cam and it ran 11.3 @ 119 (1.5).....switched to the AFR heads and single plane and it has been 11.3 @ 125 (1.8)....the car now dyno's 380whp NA ....the AFR head combo is fairly new, I have spent the last year or so working the bugs out as I have been able....the combo only has about 7-8 passes on it so far.
I don't see it as a big issue...casper383 is running the same basic engine except for as cast AFR 195 (280cfm or so)heads and a stock vic-E...he has been 10.9@122 NA

I just wanted to hear his reply.

making 600 FWHP from a 383 is going to be tough at <7k rpm and a stock computer. itd be a lot easier running xfi and a converted single plane where you can peak at 7500 or so and really take advantage of a nice set of ported 227s. thats where a smaller solid roller helps out, just squeeks as much power below 7k that you can get.

As is always the case it depends on 1. how either is applied and 2. what is significant. I would consider the test FastFatBoy is referring to as an anomaly. Either something was wrong with the first setup, or more was changed that is not listed in all probability. You are not going to swap to a 4bbl TB from any decent elbow and see 60hp gains solely from that small change. In your case, maybe 10 #'s, maybe nothing. One way to find out.
Actually, that is ~160hp difference. Either way, Dwayne is correct. I apologize if my post was confusing in some way.

No porting to the heads they are TEA 230cc(NEW) LT4 heads they flow as .314 and my cam is a comp 255/262 108 LSA with a .604 lift. The intake is ported but not much you can do with any of our intakes
I would go single plane like others but that involves cutting the hood and more $$$$$$
My exhasust is 1 7/8 LPP headers dumped before the axle into single chamber flowmasters sounds evol.

I was shooting for 500rwhp through an auto and a 9 inch rear. I will dyno again soon to see how close I am.
I agree with Puck. Everyone I told about my combo said it would not run well....it seems ok with a little bit left, I see some low 10.40's later on. When I was stuck in the 11.0's everyone cracked me about it.

I was talking about stepped to 1 7/8
http://lpparts.com/store/page6.html
They are fairly new and cheaper than Kooks but I think they do just as good
I just got home and looked at the build sheet and notes they actually flow at .310cfm I dont know why I was thinking 314 I do have a flow sheet you got a fax machine?
