Now that I have two birds,I want to beef up the 5.0. I have a HO EEC-IV,a E303 Cam,and a GT-40 EXplorer intake. Just wondering if the GT40P'S will cause piston to valve clearance problems. I dont have heads yet but can get GT40P'S or E7'S. I know the 40p's are better just want to make sure they will be OK before I buy a set.
I’m assuming you have an E6 bock w/ flattops
Almost all get lucky w/the E7s I don’t think I heard of anyone having a problem, though some will tell you to still do a piston to valve check. Pretty sure the regular gt40 will have similar results but be more careful bigger valve and I think I herd of one or two lucky people out there. Now as for the gt40p head it has a smaller chamber and I never herd of anyone put them on an E6 motor.

I just reread your post your going w/the E303 cam now you just tighten the odds even more.
I know. I see that there are several people running e303's with e7 heads and a e6 block,so I guess I will go that way.
You'll need mass air with that E303...
X2.I know first hand about that.
I have the pigtail and meter from a 92 5.0 GT. What else do I need to go Mass Air? I found a article on hooking up the meter to the EEC-IV, is that what you did?
You need the Mass Air EEC... Most of the time they'll be ID as A9L or A9P...
Another computer to search for is an A3M or A3M1. It was a service replacement for the A9L & A9P. They are not as commonly known, so prices are often considerably less (perceived as less desireable).
I run the A3M
I would say throw the E-303 cam in the trash...or E-bay it to a mustang guy...*IN MY OPINION*, the entire alphabet cam line is junk...Lunati makes a few real nice cams with more exhaust duration...I drove an E-303 equipped 'Stang with headers/T-5 and 3.73's...it had mass-air and still refused to idle when cold...I couldn't even come close to imagining driving with an AOD behind it...definitely suffered on low-end torque...the car was stripped down to around 2700lbs and ran 12.70's on DR's...but wasn't very fun on the street.
Um,well,I have an AOD and the E303,and the car has some wicked mid-range power,and idles a little "loapy",but is great.I have 3.55 gears.When I floor it from a stop,the tires don't have a chance (255 40 17).
My experiene with the E303, fuel injection and a manual trans, was not positive. It surged and stalled quite often. It would also buck at a low (engine) speed in any gear. When it did idle it sounded pretty tough, but what a PITA.
When I swapped the long block to another car, it was carburated with an automatic (with a stall converter). Then it was pretty easy to live with.
The fuel injection set up may have run better with a custom chip tuned on a dyno. I had a mail order one (specifically listing surging and stalling as the main runablity problem). It helped, but it was still miserable to drive.
Most of my reading on the computer is not positive for the E cam.
I think I read this on corral which made me laugh they stated there’s only 1 E-cam out there and we keep passing it along to the next guy.
Yea alot of people told me to sell the E303. I decided to go with a stock HO cam instead. That way I dont have to find another computer, plus it isn't going to be my race car, I have the 87 for that.
I hope you're not using the stock T-bird short block. If you are those pistons are going to bend the valves on the GT40P heads.
Yea stock short block,E7'S Ported with beehives.
If you haven't spent the money on the beehive springs yet, you may want to reconsider a conventional spring.
I found they weren't worth the extra cash, despite all the hype. Getting them installed correctly was a hassle. Ended up milling the spring pocket and using a stepped retainer to get the proper installed height. This was all at additional cost, over and above the price of the spring set. Of course, the hype tells of lighter weight and superior valve control. I did not experience better valve control, they floated at 6,300. In this case I could have bought titanium retainers and conventional springs much cheaper (about 1/2 the cost) and had better valve control.
Beehive springs were developed for SBC, which has clearance issues between the retainer and the rocker arm. The small retainer of the beehive eliminates this problem. A SBF has plenty of room for a conventional retainer and rocker arm clearance.
If you have a SBF, beehives can be a pricey and unnecessary upgrade. It was for me.
Thanks for the info 86. The heads are already ported with standard HO springs,so I will leave them alone. Do I run the Mustang spark plugs or the T-bird spark plugs?
Stang plugs should be a good starting point...
Whats you gunna do with stick?LOL,I love how the E cam gets battered,It's a decent cam old school maybe?,It's got its merits if you no how to match it up and dial it in.
When I install the 5 speed,I'm going to kill my rear tires quick,then,install new tires and enjoy the car.
If your using the GTP heads you can’t use mustang spark plugs
I believe he listed ported E7's as head he is installing...
Yep installing the E7's. In the process of tear down now.Anybody got shorty headers for sale? I have stock stang ones on there now,looking to upgrade.
No headers,but I do have a complete set of brand new spark plugs for E-7 heads still in the package if you are needing any.
Sorry Vinnie...it was a "B" cam in that 'Stang...not an E cam...I still don't like any of'em...lol. I'm about as stubborn as an old mule too.
I was checking out some ISKY cams and they have a nasty low end cam...idle like stock, should work well with SD and stock valve springs....I can't remember the guys name here (I just woke up and am extra lathargic, cut me some slack) with a 10:1, "P" headed 5.0 with a Comp Magnum 266 cam and from my research that's a nice entry level all around cam...he put his new exhaust clip up...I'm sure you guys heard that...idled so nice...zero surge...I think that was the same guy...i don't know...still not with it...where's my coffee?
That would be my car;)
Cam works great but I had to bump the idle a bit with SD (it has a 114* lobe separation angle). It bumped mine to idle at 1050 rpm in park and 750 rpm in drive when hot. Works great and I've had no probelms so far.
