I love LS series too, I'm waiting to see if GM makes a camaro with a blower intake. I hope so. My buddies 2002 TA is one wicked car, for being so heave and an auto.

Now you are asking on how many are out there? Man what is next? Looks to me you are backpeddling.
FWIW I dont think the Mod motor is better. I just know there are many out there running 6's and 7's with them and there are some making 400+ rwhp NA,which is very expensive for a 4.6 as it is a small motor. The 5.4 on the other hand can make 400+ rwhp with a relative mild setup.

how about mileage? can a 4.6 lug around in 6th gear at 1200 rpm like the LS1 can to achieve 25-30 mpg? everyone Ive known with one (non supercharged) complains about how gutless they are down low. advantage: LSx.
how about torque production per displacement? its not rare for a heads and cam LSx to see 400 rwtq in the hands of an average consumer. that torque per displacement is on par with one of the best power producing 4.6L at 333 rwtq.
you also fail to mention that most of the top mods use race gas.

He's using PI heads, think about how much more you could get out of a 2v with FRPP heads. FRPP heads flow as much as PI heads ported, a little less but very close.
This car was at VT Engines in 2004 which already made 365/411

I'll post dyno sheet if I get one faxed to me. Heads flow ~210@.500 (I), 190@.500 (E). I'd love to see what this would do with a more aggressive head/cam package
The modular is more efficient as it uses the same parts that can be bolted on many engines. Also they tend to last alot longer. We arent talking how much hp and tq it has. How many Pushrod 302's can go 200k+. Johnny Langton has a 300K 12 secondNA 2V thats running strong.

I know that's a 3v 4.6, but BBR may have something for your friend.
It sounds great at idle, but like a stock V8 when revved. A cammed OHV GM motor sounds like it's going rip your face off when you rev it.
EDIT: For comparison purposes

www.modularpowerhouse.com best TECHNICAL modular site out there. I have done some business with them when I owned my 03 Stang and they are good to work with (and Tim knows his shiznit)
I believe the current record holder is still 368RWHP in a N/A 2v motor (bored, stroked, etc). IMO unless your going with 4v heads skip any N/A plans and go straight to a blower. If you want cams go blower cams, but don't expect that choppiness you get with an LS1 or LT1 for example, its just not going to happen. The Mod motor is too limited in the amount of valve lift allowed, head flow (don't think there are any aftermarket heads for it even still) and the intake sucks. Also note that anything above 420rwhp is a ticking bomb, the rods WILL give out sooner or later.
Best bet, drop $5500 into a Kenne Bell and be done with it. Enjoy the loads of torque

4V heads arent cost effective to put on a 2V as there are alot of other components you need to do it right. Heck half of what you need and you are looking at almost 4k. Might as well swap the motor.
I like this 2V

This 4V sounds mean but I am partial to them.

i dunno, as I recal one of the posts I was reading some guy swapped 4v heads on his 2v with nothing more than the chains and followers. it was a full on race car so he didn't have to worry about wiring, but I believe the concept is sound.
the 2v sounds better than most cammed ones I have heard, be interesting to know what his idle was set at (500rpm?

I'm leaning to do a motor swap in the next year. About 9k in engine parts and only want a bore to 3.7 at most to make it a 5.0 giving the heads room to breath. I should see a solid 425rwhp. I'm not going PI heads route either. I'm getting Fords SVO heads and porting with a aggressive street cam and conservetive tune. I guess i'll hear heat on why spend that vs buying an ls1 and mod it. First, any 6speed ls1 is gonna cost me 9k+ and modding. My cars paid for, and weighs less. And with light weight mods like aluminum block, lighter k member, hood etc and im around 3200-3300 with driver.

used LS1/t56 combo = $4500.
you already have a 4.6 K-member, just modify the engine mount to fit an LS1.
only problem would be headers. don't know what you sn95 guys would use.
use the remaining ~$3k to do a cam swap and make 400+ rwhp.
