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.

ok, so he shouldve said the avg person wont make 400whp with a 2v because its lots of $$
if it were a big bore 5.4 than yea=)

There hasnt yet been a 400+ rwhp NA 2V. Right now the highest one is in the 360 range.

Check out Modular Mustang Racing, I think they have. Maybe it was a 4v, but still 4.6 liters. Plus the 366 you're talking about is probably KenB's GT right that runs upper 10's. 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.

how is the modular more efficient? I can think of a few factors towards being efficient.
one is power output to size and weight. it loses to an LSx in that category.
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.

Nope, not Kens.

This car was at VT Engines in 2004 which already made 365/411
a 4.6's isnt just a 4.6 Alot of differences in power among the 2v and 4v.

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.

Because GM want better MPG. They got rid of the 1st gen witch has a 23 degree valve angle. Gen 2 is the LT1 witch is basicly a Gen 1. Gen 3 is a all new engine. Gen 4 is basicly a Gen 3. Gen 3 and Gen 4 have a 15 degree valve angle. The only thing that swaps in all Chevy Hydraulic Roller small blocks is the roller lifters. The ZR1 is a Gen 2 block with DOHC heads. It was made as a performance only engine and it cost a but load of money. The ZR1 is bad *** but Chevy need to replace that tried old block. They needed a new engine that can be used in truck, SUV, and their performance car, the Corvette. In 97 the Gen 3 showed up in the vette then in 98 in GM's F-Body then the in their trucks in 99 then in the SUV in 2000. AND THATS WHY

They Wanted A Powerful Universal Engine That Doesn't Cost Gm A Butt Load Of Money

Damn, where did this thread get

He has actually came across a set of used cams that someone on Stangnet is selling cause they're going FI. I don't remember the specs but I'll ask him next time we talk and post up....

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? )

caseypayne69

Nah, thats 368 on a 4.6 not stroked or bored. But I don't think he's the holder anymore for 2v's. I believe someone has achieved 500fwhp, which is around 420fwhp on a 2v 4.6 in Modular Mustang Racing. And from a ls1 owner telling a 2v Mustang owner, that blower is the only route for power is like a Viper owner telling you that.

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.

you dont need to go out and buy an LS1 car. you can swap an LS1 into your mustang
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.

lol, thats cool and all just not my bag.

How can he do that when the cylinder heads ports are different? He would need the intake to fit it, which also required a new TB as the 2V one doesnt fit. Plus the injectors of the 2v would starve it.
