My point is that the 347/gt40 intaked motor was no where putting out any thing close to 400rwhp.
These intakes shut down at 5500 on a 302 and even earlier on a 347 because of long runner length.
The point is there are not many 331-347 based strokers putting out the 400rwtq+ which shows the high efficiency of the combo, and a great majority are well under 400rwhp.
The mustangs turn good times because they are usually very lightweight.

LS1derful, wonderfully put. I am not in the middle of the ford/mopar/chevy debate.
I love the technology. You have to appreciate what the general has done with the LS1.
I am just pointing out the fact, that N/A ford development is quite far behind. It is not like someone cannot put the combo's together, because I am very sure that LS1-like N/A numbers can come from the ford.
With the LS1 it is harder to get it wrong. You have the heads from the start, and the good porters/programs are pulling high low lift flow and 280-300cfm@.500". You have the LS6 intake which seems to do well up to around the 450-500rwhp mark N/A. The work is done and most of the combinations are well known.
There are not as many examples on the Ford side and I would like to see Ford guys not having to rely on blowers to take on the LS1.

Aluminum Canfields are not iron oem type heads and you know it, you said similar power to ls1 with better heads that sounds like both motors are modded with head work. I said 370 to 420 rwhp because thats what power modded LS1 is making these days. You cant remember your smog legal cam specs? Your car weighs 3500+ lbs? Come on i still call B.S.

I think the LS1 could hit 400rwtq with a "smog" cam in the range of 218-224@.050", I'm sure it has occured on many occasions.
I think for this discussion, that aftermarket heads such as the TFS TW, Canfield, AFR make for legitimate comparision against ported head LS1.
I'm saying look at the frequency at which these events occur.

well i read muscle mustangs and fast fords. what u ford guys over look is that the heads have been polished and ported for better flow. also they uped the compression to 10.0:1. not to mention the exhuast manifolds where ported and polished also. so i would say the engine is max out n/a. <img border="0" alt="[shoot]" title="" src="graemlins/gr_guns.gif" />

well read it again. i have the artical right in front of me. <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> i can see headers
making a differance. but i don't see a huge gain. that and they would have to be ported to match. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

i don't know u tell me. a hugh gain to me is about 20 to 30 hp. because i went form a flowmaster to slp's loud mouth my car went from 305 to the wheels to 330. and the car is all stock.

well with slp headers i can gain anther 41hp. the cat-back is all i've done to mine. do u think that mach 1 can produce that kinda gain? i don't think so. i'm not trying to **** u off here. don't forget about that lt5 in the zl1 vette. 410 hp. with out mods.

I will respond to the original post, since this has got WAY off topic.
Of 331-347 cubic inch strokers.
"My thoughts are that there are too many of these fully built combo's that fall really short of the type of bar the LS1 has put up.
Built right, these cars could put down similar numbers in similar RPM ranges."
----I would say that since there are alot more 331-347 inch strokers out there than heads/cam LS1's, than your success/failure rate will always favor the LS1 since you are starting out with more base HP, and there aren't the same amount of cars for comparison. I would say alot of fully built combo's of every make fall short of there potential.-----
"I remember when the bar for LS1 was 400rwhp, then 420, then 440 and now it appears to be in the 450-470rwhp range for hydraulic cammed, street cars that don't need to rev to 7000 rpm to make their power. The rwtq is phenominal too, looks like the really good combos are in the 400-430rwtq range. This is a true testiment to the EFFICIENCY of these combos."
----The current output of a heads/cam LS1 is VERY good. As for the 450-470rwhp cars I've seen, they DO need to spin 7k+ in order to make there power. Nothing wrong with that, but I havn't seen any hydraulic cammed 470rwhp LS1's peaking at 6,200.---
"Most of these ford 331-347's are putting down around 350-370rwhp and 350-370rwtq. This is a far cry from the current LS1 development."
---You're probably right. But just because most people aren't building them right, doesn't mean that there is no N/A ford engine development. I don't see you using bottom of the barrel LS1 cars for your comparison. A properly built 347 with good heads/cam should make similar power to an LS1, if built to make peak HP at the same RPM. In fact, I can't think of a cylinder head that more closely resembles an LS1, than that of a small block ford.----
"On that side they are saying you guys spend ALOT of money to get the type of power.
My thoughts are is it costs in the $4000-$7000 range.
Heck some of the shops such as LG or MTI should put out ford packages for the ford guys so they can get a taste of real N/A power. "
The LS1 cars are comparitavely expensive, but that's no suprise given how long they have been around.
Your original question is about N/A Ford engine development. But then you bring up examples of 347's. As someone else stated, that engine should be compared to the SBC, as it's architechture is from the same era.
You can't really compare a SBF to an LS1 in terms of N/A development, because the LS1 had the latest technology in 1997. Just because we can do heads/cam and bolt-ons and make outrageous horsepower doesn't mean we're ahead of the game with engine development. It means that GM's LS1 is ahead of Fords small block in terms of engine development, and it should be considering it's 30+ years newer.
If you really want to know about naturally aspirated Ford development, look no further than the ohc modular motors. They will not have the capability to make the same streetable horsepower, in the same RPM band as an LS1 due to a serious lack of cubic inches, but they really shine with forced induction.
And before I hear any "give us 32 valves" or "give us a blower" remarks, remember that those comments are really irrelevant, because that's NOT THE WAY IT IS!
Fords are 4.6l, making power with 4 valves per cyl and overhead cams, and in some cases boost.
LS1's are 5.7l, naturally aspirated.
If all the variables between both engines were equalled out, than obviously both engines would be identical and there would be no debate.
