Can I use mustang OEM shorty headers on my 93 F-150 with a 5.0 instead of the stock exhaust manifolds?...... will it also help performance?

 

Yes and no. Yes, 302 shorties are 302 shorties, and headers are always good. BUT on these pickups the Y pipe is extremely restrictive, and will negate anything good that comes from the aftermarket headers. You will need to get a new y pipe to really see any decient improvements

 

would they be a direct bolt in, or is the flange different? I can get a new Y pipe later

 

Mustang headers have a slightly different angle on the collector. You will most likely need to have a custom y-pipe made. It would be cheaper in the long run to use headers designed for the F-series/Bronco then use an off the shelf performance y-pipe such as Bassani. The factory y-pipe is very restrictive.

Several members have used long tube headers on their trucks with good results. If you have a 4x4 they may not work as well due to the extra bends to snake around the transfer case. I recently replaced the entire exhaust on my '92 4x4 F350 w/5.8L. I stuck with factory manifolds due to the extra cash$$ for good quality stainless steel headers. My motor is bone stock. If I ever add better heads or intake I will swap in shorties. I used a Bassani SS y-pipe designed for a Bronco. Very nice piece. From there I used a single 3" converter, muffler and tailpipe. All the pipes are mandrel bent. It flows very well, the sound is a nice rumble at idle, no in-cab drone and a nice deep tone at WOT. Much quieter than the full Magnaflow exhaust on our '97 Mustang GT, but it still does turns a few heads when I fire it up. As I have stated before get a good quality 3" exhaust, control the sound level/tone with your muffler of choice.

 

ty for all the info, reason im askin is Im gettin a set of shorty's and an E7 lower intake for 10 bucks.... figured the price is right. Is the E7 the H.O. intake? would i benefit from it? or maybe just the injectors?

 

Not sure about your intake being an HO version. My Mustang is a mod motor. My old Lightnings already had GT40 pieces. There is not going to much if any difference in the injectors from the Mustang to your truck. Both are 19 lbs. injectors, they flow the same. If your injectors need replacing then it might be worth a swap, otherwise no big gain.

 

Cool, thanks alot.... might be useful to media blast it and paint it then just swap it out with an unpainted one

 

You can't bolt a truck upper on a HO lower, the port shape and size and bolt locations are totally different. That's the HO lower on the left and the 5.0 truck in the middle. The one on the right is the 5.8 truck.

 

So how did the guy with the 5.8 upper bolt to the 5.0 lower.... bolts look to line up, but would it make any difference... looks like the 5.0 one would flow much better

 

Bolting a 5.8 truck upper on a 5.0 truck lower can be done but there's no point, it creates a bad port mismatch that hurts airflow more than it helps. The 5.0 truck intake is really too big for the motor, if you want a TQ boost swap on a complete 5.0HO intake(upper and lower), the TB and EGR electrical connections will have to be moved and the intake tubing changed to a single tube setup, but that's not a hugh deal.

 

Are the 5.0 HO non MAF connections the same as whats on the truck now? i have access to a 5.0 think its an HO motor over at a buddies in IL. Wont the egr tubing not match up?
