    Good Morning Mike

    The HP06 300hp 336tq 302ci crate engine uses a high performance camshaft like what you have listed, and the heads are also bowl ported to help flow. The compression is also a true 9:1, when Ford built these engines they were mass produced this result in the compression ratio being lower than 9:1. Please fill free to ask any other questions you may have Mike.

    Subject: 302 for 90 mustang with aod

    Matt, I'm looking for a 302 to replace my current tired motor and I'd like to stay efi. I'm curious how do you achieve the advertised 300 horsepower with e7 heads and a .498 lift cam?

    300hp is not unheard of with stock E7 heads. There are even guys doing that at the rear wheels. There is probably some port work done as well on those heads, but the bowl area is a large restriction on the E7 head. I don't doubt that it gets close to that number.

    I used to see guys waaay back in the late 80s running high 11s with worked over e7s,cams,ported intake. 300 fwhp isn't out of the question. Maybe a little optimistic but not by much

    Hm y'all think its bout right? I was thinkin it'd be a little over rated seeing reports of the fellas getting the ford racing crate w the gt40 crates and being disappointed with them and such. I just have time believing that atk making 300 hp w stock heads

    Well they are probably over rated like you think. I was just agreeing with revhead that with a little work e7s can flow a lot better than stock. They still suck lol. That engine probably only makes 260-275 fwhp with a carb setup

    you talking wheel hp versus flywheel hp. a lot of the gt40p guys are in that 270-290rwhp range, which after driveline loss is (roughly) around 300-320 flywheel. with the right cam/intake and some porting, i wouldnt doubt that an e7 motor could get close to that.

    The Ford Racing engines are rated using decades old "gross HP" ratings, if you can believe it. The factories haven't rated their production engines that way since the early 70's. Lop at least 15% off the stated HP of those engines for a more accurate, real-world, flywheel HP figure.

    Nope I was talking rear wheel horse. Alot of threads are reporting they went to the chassis dyno and got somewhere in the 240 horse range.(do a search as they say) As being built for tough.... It might be tough but I don't believe it's made by ford. I think its assembled in Mexico or some sht like that. I wonder if it comes with the Chinese ford racing water pump or is that sold separately? (Yeah I know accessories are separate I was just making a reference that for racing parts aren't made by ford...). But maybe that gt40 crate wouldn't be too bad, it'd be hard to find labor for cheaper if you were to rebuild your old motor.

    I actually purchased this engine about 3 months ago. I've liked it so far. They claim to have made the 300hp with a Weiand Stealth Dual Plane Intake along with a 650cfm carb and a set of 1 5/8 dyno headers, the (basically) E303 cam and the bowl porting like you say. I have an AOD with the still stock 2.73 (i'll be upgrading soon) so the car launches like crap, but once it gets going it pulls strong.

    Comes with a 3 yr unlimited mile warranty.. I doubt the 300 HP number in the real world application, but it seems to be stronger then the original engine - from what I can recall of it.

    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

    IMO,,, stick a $300 JY explorer motor in there with upgraded valve springs and a decent cam and you will be around 280hp for a whole lot less money. Those motors go 150-200k miles like clockwork,

    My current Mustang has not been to the track.. Either before or after the swap.. so I can't say for certain.

    I have a convertible AOD.. obviously not the best combo for power..

    If I had to guess, it's probably low 15's in my car... But it really is just a guess. I've heard of stock convertible/AOD's doing 16 second quarters... So it does feel quicker to me. Here is what I have in the car.

    1989 Convertible LX w/AOD:
    ATK - HP06 Engine, K&N Panel Filter, PRO-M Mass Air meter, 65 MM BBK Throttle Body, stock ported and polished intake, MAC H-Pipe w/cats, Flow Masters, Flex-A-Lite fan, and Under-Drive Pulleys.

    That was another option I looked at, I could have gotten the engine for $700, but the non-roller motor didn't make nearly as much HP and I wanted something I could enjoy and not have to worry about constantly replacing stuff/downtime.

    Uh... the 5.0 explorer motors are a roller, unless you were looking at a pre 1986 block. The non HO cam is still a roller cam, just a milder grind. $700 is still a bit high for that motor. You can get them all day long for under $500 at most JY. The pre 97 have the same EGR steup as your Mustang motor.

    As far as ET, you're lucky if you can get mid 15's with that setup. I have a 90 LX vert with an AOD and the following mods

    Explorer intake, heads, 70mm tb, 70mm MAF, headers, H pipe, flowpath mufflers, 3.73's, E fan, U/D pulleys, and some other bolt ons. I bet my car is a mid to low 14 second car and Im probably around 260hp. Next is either a shift kit or a silverfox valve body.

    First thing you need is 3.73's and a shift kit to wake up that AOD.

    I have a running 302 w like 180k on it. I could slap gt40s on it and have the same worn motor I could get from JY but kinda want fresh bottom too

    With my kind of $ I don't have expectations of being super fast I just don't want to be comically slow either. 14-16 sec 1/4

    Yes, gears are definitely the next thing I'll do. Actually was getting ready to order them once I get my summit bucks for ordering the K&N filter through them (my old one was all dry rotted)..

    You recommend 3.73s over 4.11? I was going back and forth between the two? What's your RPM at like 80MPH? With the 2.73's I'm at 2k. are the 3.73's still under 3,000?

    my old 89 T5 GT, with mods similar to this one and 3.73 used to run 14.2... With a 90LX AOD, I suspect you would be high 14 low 15s with this motor.. Again, just my best guess.

    Some guy posted a youtube video after he had the ATK engine installed. You can hear the lope when he gets near the exhaust

    View: https://www.youtube.com/watch?v=wK8U3iGZ76w

    The guy doesn't seem to know what he's really talking about, but he claims he had it at the dyno, where it did 224 at the wheels. That seems like it's more then the car would have done with the original engine - even taking into account his mods that were already done - someone else can chime in for certain, though.

    I have 3.73's in a 95 5 spd car. They are ehhh alright but it's still slow btw. W the 3.73's it feels like it needs a 6th gear on the highway and 1st is rediculously short. I kinda wish I went with a higher gear really. They didnt make er a rocketship or anything more like a semi truck. Maybe if I had a good set of heads it'd be easier to live w and justify but shifting my azz of and still going slow- no fun
