Anyone see the recent MM&FF article about Steve Matusek's Pro 5.0 modular? He's running a 5.4L BUT, destroked it.

I dunna know...for a street car it seems like it would makes sense...all that torque down low in the "everyday" RPM range has got to be a good thing...even if the horsepower numbers aren't significantly better than a 4.6
thats the main point of it.. the extra torque.. red has his torque come on quick, his is almost at 300 ft lbs at 2200 rpms.. now try that with a 4.6

My 4.6L makes 600rwtq @ 2200 rpms.
I HATE YOUJK After doing all this research and wanting to go TT for big numbers I decided KB is the way to go. TT I could get a 725 rwhp monster thats almost impossiable to drive on the street or go with a nice 450 rwhp that is there by 2K and have a much nicer driving experience. I dont need 9 sec time slips or Mclaren F-1 speeds. After driving a couple Termis I like the idea of a little motor behaving like a big block with better mileage and less weight, guess I am a little old skool.
wrong, the guy isnt doing the labor, and its not easy at allum i would say look into a 5.4 swap with cam's its easy, and doesn't take to much to get it to work properly
whats your point? 30rwtq or so for a complete motor swap? Retarded, put a lower gear in the car. Torque when racing can be compensated for through the modifications of the entire car, as gearing etc. No doubt torque is very important, but a motor swap for a slight increase in torque? Not smart. I was the first person to ever run reground cams in a 4.6, and my car mad 319rwtq UNTUNED and STOCK TIMING. Big deal, its still weak.you get loads of torque. its a nice way to get power for a N/A car. because just remember, there is not replacement for displacement
I read your link, it only confirmed the truth, the 5.4 is a waste, you got suckered in to some guy that did the swap since your a newbie to 2v's and thought you knew what you were talking aboutalso a 5.4 2v built PROPERLY can have as much HP as a built 4.6 4V, with more torque. you need to read some on the 5.4 swap before you dis it..
its do-able, just find the right parts...
now see here is word that it is possible... straight from a guy that has done it, and helped a few ppl do it... if you read his is only expensive because it is built with lots of work done to it
I'm the guy he's quoting. Your own ignorance and doubts aside, all things are possible with effort. You should really read up before you shoot people down. I started my swap on a 1000 dollar budget and made it but then the week I was gonig to drop it in I decided to do a built motor and spent another 5500 bucks getting there.
Most of the people who've done the swap did it with the stock tune and later got a performance tune. It'll run just fine on a stock tune and with stock heads and cams and a PI intake on adapter plates 280/350+ is not uncommon after the tune. With a proper 5.4 specific intake(modded L intakes, custom, or HPS's new intake), longtubes and stage 2 cams you can easily pull 350rwhp/tq out of it on pump gas.
If you're going to be a jerk about disagreeing, at least have the courtesy to be correct or educate yourself by going and reading the 109 pages of that thread dude linked. It's perfectly cost effective if your goals are in line with the documented results.
Just because it's not your limited view of the way things should be it is an option, it is sick fast and cheap and easy. Get off your high horse kiddo.
BTW... a basic 5.4 swap with a tune normally yeilds 50hp/tq over a tuned NA 2v 4.6 even when hamstrung with adapter plates. Yeah...that's nothing huh.
and yea more torque is a performance upgrade last time i heard, OR wait never mind according to what i am reading from you.. torque ehh who cares about torque its not a performance upgrade..
he asked for idea's i gave one and you keep on bashing me and R3dn3ck on it.. STFU..
otherwise 2V heads are just not good enough to supply the air requirements of the additional displacement
Definitely some misinformation in this thread. The biggest glaring one is "The 5.4 flows better air and therefore produces more torque." It's the additional stroke that produces the additional torque. There is no question that the additional torque is driver friendly and appears to produce more power in a DD, but in the real world, that is a ton of expense and work for little gain. Like others have stated, I would much rather put my 2K into mods for my 4.6 2V for better results than the swap alone would produce. That's just my .02

but dd street were torque is wanted i don't see how its a bad thing.
Part of the problem is that the 4.6 and 5.4 have the exact same Bore( 3.55" ). The 2V heads in stock form are not adequate enough for the 4.6 to be a performance motor, how the hell can they be adequate for the 5.4 which is moving more air. This is the reason for the big Torque of the 5.4.
