My dad looked over the modified tune and was unsure about the mid-range boost section in the fuel table ([email protected] to [email protected], that general area). I told him I'd ask about it, he thought it should be richer since that's closer to the peak torque (or so he thinks anyways, don't have a dyno sheet). Post some convincing dyno sheets, dyno vids of GT40 Iron headed comboms putting out some nice #'s (300RWHP+) you must have all accessories hooked up. anyone can make more power with no smog, no a/c, no powersteering, and electrice water pump.. A typical aluminum headed H/C/I with a tune puts out 300RWHP + with full accessiories..
Many people ask us here at 1A Auto what the difference is between an exhaust manifold and a header. Well, today is your lucky day While exhaust manifolds and headers play the same role in engines, namely channeling exhaust away from the cylinder head to the exhaust pipe and eventually out the back of the vehicle, there are important differences between them. 253hp/303ftlb on a Mustang dyno. GT40P heads, Explorer upper/lower, E303 cam, 65mm TB, 75mm MAF, 24lb/hr injectors, FRPP shorties, Mac o/r prochamber, flowmaster 40s. Weighed in a 3106lbs before the lighter wheels and Al driveshaft, so it's probably just under 3100 now. I dont know how much power i gained but I dropped 6 tenths off of my times from 13.7 to 13.1. I bought the X heads when they first came out many years ago and now they are supporting 500HP to the tires with my turbo with 10psi.

Basically, they added and then swapped and ran every combination on the dyno to get a yea or nay on whether it was a real improvement. I was very happy when I found three components that I have on my setup in the mix: Holley Systemax intake, e303 cam, and GT40p heads. Even though Ford didn’t take any Obama money, which was a good decision, they could have developed a better cylinder head than the currently available 351N heads.

351 Cleveland Cylinder Heads Guide: Factory Iron Heads- Covers Engine Building and Performance Updgrades to the 351C, 351M, 400M Ford Cleveland Engine Ive only found a few setups aod thats gt40p only making 240-250, more so are 260-280, the non p heads seem to average 245-255ish.. but theres still a good bit at 290-310 with sheets witg p heads and even a few with no porting or valve changes.. I think someone on here was advertising some Crites headers that I thought also worked on a 302. They looked like they would clear GT40P heads good because the tubes went straight down then back, but their kinda pric-ie $350~ plus shipping, for much more than that u could just buy a different set of heads lol and save ur self the aggravation. When we find a procedure or an item that will increase the torque and the power levels, we will offer it up. However, we will try to be a little bit different, as we will share all the data we have noted on those items, from OUR own cars, with actual road tests (SOP meter) and the Dyno sheets. One of the mags did a test last year, where they dyno'd a bone stock Mustang 5.0L, then pulled the stock heads, cam, intake, tb, headers, etc. and bolted them onto a 347 shortblock, then dropped the hammer. The 347 only made 25 or so more horses then the 302, but a but-load of low-end tq.

When I was helping out a friend of mine, somebody brought in a GT40P crate motor that was supposed to be producing 400 flywheel. It didn't come close to that and the heads had been lightly worked on that engine. 340 or so.
Right in the same ballpark as the AFR head are Trick Flow heads, which do a pretty good job on small-block Fords. The rest of the market, Edelbrock, Ford Racing, and World Products have good cylinder head castings for the money, but few of them perform as well as AFR and Trick Flow on the flow bench and in the dyno room.

Put on some GT40P Heads with the upper and lower intake. Along with some other basic bolt-ons, and I can't wait to get it to the dyno to see how much power I'll make.
