I'm a little surprised by your choices.  Where would you rate headers and underdrive pullies?  Any header recommendations?


Also, a free upgrade is bumping the timing to 14 degrees.  That's supposed to be good for about 7 horsepower.

WELL I WENT WITH MY CHOICES CAUSE THEY WORKED REALLY GOOD ON MY 86 NOTCH.HEADERS ARE A GREAT IDEA,I WAS JUST TRYING TO STAY ON HIS BUDGET.HAD A SET OF MAC NICKLE PLATED SHORTYS ON MY CAR(EQUALS) ,THEY WORKED WELL FOR ME.I FOUND MY EXHAUST COMPLETE IN ONE OF THOSE CAR PART MAGS -HIGH FLOW H-PIPE, FLOW CAT BACK (2 CHAM)AND HEADERS FOR $350 .THAT 14 DEGREE TRICK ONLY WORKS ON SOME OF THE CARS .MINE WOULDNT TAKE IT W/SUPER.NVER WENT THE UNDERDRIVE ROUTE.DONT KNOW PEOPLE SAY THEY WORK ,I DONT KNOW.THE ONE THING ABOUT BUMPING THE TIMING IS THAT YOU HAVE TO RUN SUPER TO PREVENT DETONATION!

Once I took my timing to 14 I always ran higher octane gas.  It worked pretty well for me.  I could feel the difference. 


The same with the underdrive puleys.  It made a noticable difference. I was actually really surprised in both cases.  I didn't think the change would be noticable.  


Of course, maybe it just seemed quicker because I wanted it to seem quicker.


I would switch my car over to the improved dual exhaust if it weren't for the ridiculous California smog regulations.  They make it really difficult to modify your exhaust and the '85 Mustang has dual ehxhaust into a single cat and then back into dual mufflers, so I went for a massive cat.  It made a surprisingly big diference too.  I'd go for true dual exhaust in a minute if I could though.

I have an '85 LX hatchback/sunroof with a T5.  It still has the original 7.5 inch 2.73 rear end so I went for a torquey Crane PowerMax 2020 (.530 lift, 262, 270 duration) cam. I also have JBA shorty headers, Edelbrock Performer with EGR, March underdrive pullies, flowmaster 2 chamber mufflers, Catco 3 inch CAT, pocket ported Windsor Jr's, Comp Cams Pro Magnum roller rocker arms, Maximum motorsports strut tower supports and 4 point K-member support and BBK subframe connectors.


It goes okay I guess...  If I get a chance to switch over to a 3.55 rear end (wife and 2 1/2 year old rugrat allowing), I'll probably switch to a higher horsepower cam....   that's the pipe dream keeping me going between diaper changes anyhow...


Since I believe that CA smog rules limit my manfold choice to the Edelbrok Performer EGR or a Weiand Stealth (EGR version), my cam choice is limited by the RPM range of my manifold.  I chose the Edelbrock because I wasn't sure of the hood clearance on the Weiand.  That's why the 5,000 RPM Crane 2020 made sense.  Later, If I change to a higher RPM CAM, I may go with the Weiand Stealth, since I now believe it sits as low or lower than the original Ford manifold.  Any ideas on the Stealth vs. the Performer EGR (height and performance wise)?

What is the better intake manifold? 5.0 L codra or gt40? And what is the gt40 upper and lower?

I have a Stealth intake on my Coupe. I have a 1" spacer on it and a Holley 650 DP. My air cleaner is a 4 1/2" K&N Extream with a flat plate. I have a 4" Cowl Hood. The air cleaner has about a 1/2" to 3/4" clearence at the front of it. You could set you car up with out the spacer, and get a drop plate for your air cleaner and I think it would fit under a stock hood. Performance? I really don't know yet. It's on the car but I haven't had the time or money to finish the car yet. I have a 2 year old at home too. I feel lucky to still have the car let alone finish it. They say the Stealth is good to 6800 rpm. I have an Anderson N-5p cam that has a 6500 rpm shift point so it should be a good match. Time and ET will tell if it is or not.

That sounds like a very nice setup.  Would a drop plate on the air cleaner work with the stock air cleaner?  I'm in California and the smog rules make it difficult to change some really simple things. 


So you're using a carburetor and a supercharger.  Sorry to ask again (I think you mentioned which model you had on a previous post) but what make/model supercharger do you use?


I'm probably not going to supercharge, but I can always fantasize.


Off to watch my Hotwheels Highway 35 "World race" video with my 2/12 year old.  Don't laugh too hard, after seeing it fifty times, it is not nearly as mindnumbing as Barney.

what is the gt40 upper and lower (intake) mean?

The upper and lower intakes are intake manifolds for EFI systems.  I don't know much about the different options on EFI setups, but I believe that there are two parts to the manifolds on the Mustangs (upper & lower). 


You should probably start a new thread on this where you describe that you are comparing the Cobra and GT 40 upper and lower manifolds.  Also, ask if someone can explain the RPM ranges where the manifolds perform well.  Since your motor is relatively stock, be careful to avoid parts that are for extremely high RPM use.  Try and get parts which all perform well in the same RPM range.  Don't select parts just because they promise a higher horsepower number (they are usually only attainable at RPM's which the rest of your components will not perform well at).  Your stock 93 heads have a very restrictive exhaust port which severely limits horsepower over 4800 RPM, so a high RPM manifold is not going to work really well for you.

"GT-40" is the name Ford gave the intake design.


The "lower" intake bolts up between the heads with 8 runners(air passages) diverting off to each cylinder head port.


The "upper" intake (plenum) bolts on top of the "lower" intake with the 8 runners converging from the lower intake up to the 1 main throttle body/egr-spacer opening (this is the large intake piece right on top of the engine, that you see when you open the hood.)

Do you know the name of the stock manifold? How many RPMs is it good for and about how much horsepower can it handle?

It just refered to as "stock".


It doesn't flow very well compared to what's available, usually falls flat around 5K.  I don't think it's good for more than 300 flywheel horespower ......... on engine alone.
