What do you think of N/A Ford Engine development?
Right,I work on these cars for a living and have built more than 1 347 combo that would be right next to a modded ls-1 You'd better know who your talking to before you make statments like that.
<strong> ]Wrong, iron headed small cammed 347 will not put out same rwhp as modded LS1. Not even close,you better look around here awhile before you come out with statements like that. </strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Right,I work on these cars for a living and have built more than 1 347 combo that would be right next to a modded ls-1 You'd better know who your talking to before you make statments like that.

You are saying 331"to 347" 5.0 based motor with slug iron heads and emission cam is making 370 to 420 rwhp? You are a professional glue sniffer! <img border="0" alt="[bullshit]" title="" src="graemlins/gr_bs.gif" />

To begin with I believe the poster was comparing pushrod engines, not overhead cammed engines.
From what I have seen the OHC/DOHC aftermarket is not very big at all and its developing slowly. Stock vs Stock the LS1 heads outflow Fords pushrod or OHC/DOHC heads. As a result you can see pretty significant gains from just a cam swap as compared to a 281 or 5.0 stock heads. You really can't compare modified to modified heads because they can be manipulated to suit different needs. You can see this in compeition heads where constraints limit lift, i.e. 300+cfm @ .5" and thats a figure from a Ford head.
As far as displacment and power, well a 281 can be setup to closely match a stock LS1 power curves BUT when it comes to pushing the envelope of both engines on a street setup, your gonna see how those 65 extra cubes are going keep you ahead of the game.
If you want to compare apples to apples, LT5 Vs Modular. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
<strong>I personally have never seen an NA 302 based motor (including stokers) that has performed impressively that runs on pump gas. That doesn't mean they are not out there but just that I haven't seen one and that includes some 2800 pound cars. </strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">What's your definition of "impressive?"

There must be a whole bunch of stock cube mustangs running mid 10s in daily driven cars huh?

He thinks i dont know anything about Fords he is dead wrong, and i noticed he has no response to my questions.
<strong> I don't really want in this war, but I saw a bone stock 02 Z bust a 00 Ford Lightning by at least 3 cars so don't come on here saying that the highly overated Ligtning motor is worth a crap. </strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">the fact that the lightning is a truck weighing nearly 4800lbs has NOTHING to do with it losing either.
<img border="0" alt="[punch]" title="" src="graemlins/gr_punch.gif" /> It out over at LS1.com
Mustangs have like a billion options when it comes to intakes and cylinder heads, I think we'd all pick up big power if there were intakes out there that worked for our cars.

<strong> Impressive equals low 12s to high elevens. </strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">A local friend of mine has a '92 hatchback car with a mild 347cid stroker, 10:1, TFS heads, hyd. roller cam, GT40 intake, basic stuff (big throttle body, MAF, headers), T5 tranny, and 4.10 gears. The PCM is totally 100% stock, and the car is most definately not tuned to it's full potential. It's had some weight removed, but is by no means gutted.
Two weeks ago I personally drove the car to an 11.51 @ 117mph the first time I'd ever been behind the wheel. I was pretty impressed, considering his entire motor probably cost less than my heads/cam. For what he paid for the complete assembled shortblock, I could buy an LS1 stroker crank and a Happy Meal at McDonalds. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
I love my car, I think it's pretty dang quick, but LS1's aren't the only game in town. Personally, I was quite impressed with that mid-11 second ride. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
