Stubborn people like myself. At least it's not a hijack. It is very much on topic.

Indeed. 300rwhp is a struggle for a bolt on Fox body with GT40/GT40P heads. Now....show me the thread on this website where people are knocking out 300rwhp with E7TE heads on a bolt on Fox body....or even 300fwhp for that matter? As tough as making 300rwhp with GT40/GT40P castings is....its even tougher with E7TE's. E7TE's will cost you the same amount of money in the end, for lesser results!Oh man here it comes. Someone is going to recommend a Fox throttle body swap now.
Throw all the data you want at it. There is a thread on this website documenting the experience of those trying to get 30rwhp out of there GT-40P heads. Same power people are getting with E7s.

Yeah man? You think it's faster than the stock ho 302? I guess it'd be apples and oranges comparing a fresh motor to old 302 but what do ya think, is it kinda quick or is it a 15 sec 1/4 mi motor? What intake do you have on it? I too have an aod
Hi...just joined I just purchased and installed the hp06 300hp engine from Atk... on July 8th 2015...I love it I put the elderbrock performer intake upper& lower on it #24lb injectors 75 mms throttle body 76mass air meter calibrated for the #24 lb injectors 373 gears 155 fuel pump Bbk shortly headers Bbk H pipe cat back mufflers it has the t5 5 speed manual..deff runs way faster than the stock 302 it's an 1989 mustang Gt..Atk was Great! No over spray on engine when painted motor was build delivered on time dropped right in no problems I have 327 miles on it still breaking it in...customers service was Great also.I do believe they are very close to their 300hp that say...after my 500 mile break in period I will take it to the track and let you know the 1/4 mile time..a good intake and fuel delivery and 373 gears are the main thing for the performance of this motor..

Yeah I noticed they were cork gaskets but I change the valve cover gaskets out for the rubber ones but otherwise I'm happy with a motor I can run there real nice takes a good couple weeks to get the computer to learn a new cam but Atk said any questions or problems they said please call...and a custom Dyno tune will help out a lot..tuning air fuel mix is a must...I am running lean. I can smell it and the plugs are a little white. I will have to upgrade my fuel delivery.
Even with that, the car is quick with this engine even with the 273s still in. You can feel it pick up nicely at higher RPM, so I am sure it runs far nicer with the 373s you have.
One thing to watch for.. at least it happened on mine... The oil pan and valve covers started leaking pretty quickly. Mechanic said they used cheap gaskets. So, keep an eye on that.
And 373 gears really wake it up at about 3000rpm to 5500 pulls real hard big differenceYeah I noticed they were cork gaskets but I change the valve cover gaskets out for the rubber ones but otherwise I'm happy with a motor I can run there real nice takes a good couple weeks to get the computer to learn a new cam but Atk said any questions or problems they said please call...and a custom Dyno tune will help out a lot..tuning air fuel mix is a must...

Maybe the car just needs a good mass air meter and 24 lb injectors. Pro m is the way to go on the meter..I am running lean. I can smell it and the plugs are a little white. I will have to upgrade my fuel delivery.

I do have a pro-m, but calibrated to the stock injectors. The car sat for 10 year in my garage prior to the new engine.. and my confidence in the original injectors is not high. So, yes.. That is something I was looking at. I'm just at this point, where I am not certain I want to spend much more on the car... Certainly not this year. New engine/radiator 2 years ago.. Cleaning up the leaks and a new intake this year (had an intake leak too)... Maybe next year will be the injectors...
It doesn't matter what the meter is "calibrated for" if you're getting or have gotten a digital tune. You can put any high impedance injector you want into that car and adjust the tune for the meter and injectors. What matters is that the sensor is consistent, is matched to the housing that it's in, and large enough to allow the air volume needed to support the motor.
I also think you have the wrong idea about what the adaptive strategies in an EEC-IV actually do.
I didn't realize, but that makes sense. That was one of the reasons I didn't want to upgrade the injectors.. I assumed I would need a new MAM too.. Well, I guess I still do, unless I want to get into a tune.
Well, I know it can adjust timing and I thought had an impact on the A/F mix. I certainly could be wrong.
I'm derailing, but the initial point to this thread was about 300 hp from a set of worked E7s and a mild cam. I believe it. E7s are no match for any aftermarket head, but can make good power. My lowest was 256/292 to the tires with unported E7s (GT40 valves, valve job and some milling), stock cam retarded 4 degrees, cobra intake, 65 mm TB, 75 MAF, long tubes, pulleys, etc. at one point it made 272/316 in the same junk different years.
