And Steve, he's running Cartek stuff. That's why I mentioned Cartek earlier. 
Anyway, been pretty much covered here but, basically four things will dictate:
Rear gears
Tire height
Max RPM of engine
Trap speed
There are online calculators that can get pretty close, but they don't account for tire growth, trans slippage for auto's etc.. A 28" slick will grow to about 29" at the big end depending how fast the car is.
It gets even more complicated choosing a rear gear when you want to run nitrous part of the time because then you have to compromise....

I notice also that his motor is not wasting much power on smoke and drama like most H/C/I setups.
Yeah there's obviously plenty of muscle there, but the powerband seems ideal for the specific combination of factors you listed above (gear ratio,tire size,weight,etc.)
Driver's fantastic reaction time doesn't hurt either.
I'm still pretty stoked about my Thunder Racing Raptor Cam but this Cartek heads and cam package sure looks good.
This video pushes the bar even higher, really showing the POTENTIAL of an optimized stock bottom end 346 "Sorry Mike but you should be shooting even HIGHER still with your big cubed monster.)

I think you're the first person I've heard of that referred to a little ol' 370 as
"big cubed" lol.... Don't forget I also get the 80lb weight penalty because of the iron block.

I seriously considered having AC Nutter Sleeve my LS6 so I could run the L92 heads and gain a few cubes myself.
His pricing was reasonable enough that it almost made sense.
Your are right though, 370 wouldnt be considered big Cubes except to someone with a 346
Hell I dont even consider a 408, monster cubes. I mean yeah I may be one of the only ones in the portland area that we know of but look at the LS7 it's a factory 427. Then you have people like Bobby that have the 454's and One guy in gaston with a 700hp 455 in his SOM WS6.

The 370 has only 24 cubes more than the 346 which should be worth apprx. 1.25 h.p. per additional cubic inch = 30 h.p. (apprx.)
In terms of a H/C 346 car, 450 rwhp is considered strong -but 480 rwhp is pushing elite territory!
I'd certainly rather have the greater cubic inches, A person could easily spend two thousand bucks on a set of heads that may only net a 30 h.p. gain when it's all said and done.
I think Mike has a Fantastic setup with a couple more cubes and comparable flow to even the Cartek cathedral port heads, his car has a little more potential than us 346 cathedral port guy's.

I watched this video again from the youtube site and read the remarks; This guy is puttin down 509 RWHP! - Wish I could afford to go Cartek w/ my lS6.
TFS 215's are not seeming so expensive anymore.

Realisticaly though, they are more than I can afford.
I think this car really shows what can be done with a stock bottom-end 346 with sufficient engineering,time,and money.
For me though, I have to look closely at the cubic dollars in order to play at all!
Yeah I know what you mean about the whole money thing. I wish I could afford all that stuff too. I just can't believe how much these cars can handle fir the price you pay. Look at the mustang you have to spend almost a grand in cams to gain 30-40 hp...lmao.. The new boss has better cams and the heads were done and they only got 24hp over a stock 5.0.. Go figure.
That is impressive that much power from the cartek set up. My buddy bought Andy's, the guy with the ws6, old looks headers and we got to check out his car that thing is sick. His friend has a sweet vette and also a viper that was also there when we picked up the headers, defiantly some sweet cars those two have. His buddies viper was his dd he was just leaving as we got there was pretty sweet car.
I'm thinking about going with Advanced Induction to CNC port my heads and hand port Fast 102 intake.
I can't even think about Cartek, That would take all my transmission money and Mike wouldnt like that!

I did the port work on my L92's and they're flowing better than the heads on that Cartek WS6 (357/260cfm @.600). My restriction is the stock plastic intake manifold even though it's ported. The plastic intakes are great for street/strip cars, but for a drag car that doesn't see much street duty, it's a restriction. That Cartek TA is running a single plane Vic Jr and a 4bbl TB if I'm not mistaken. On an engine like mine (or that Cartek WS6), that Vic Jr intake with a 4bbl style TB is good for an easy 20-30 hp on the topend (4k+rpm). The problem is you need to cut the cowl out to make room for it. I'm still on the fence on whether I want to go that far with it or not.

When i first saw it he had just taken out he ls1, said it had ported 241 heads and cam making just over 400, thought about buying it for my jeep at the time, wish i would have he was selling it for a reasonable price and low miles. He had just put the new engine it it, I have yet to see it since then. Have you seen the corvette that I was talking about? I cant remember all the details on it now but it was a pretty nastly little set up too. How is the black car coming?

Well if you do I think you know where a buyer is lol. I am in the process of rebuilding a 408 for my car. I already have a block and I am looking at some new pistons and rods, I will be able to reuse my crank I think. I am in need of my tranny being rebuilt though. I'm up in the air between spending more on the tranny or buying a turbo k-member.
