Im wanting to learn more about my engine, i just bought my 91 F150 about 2 months ago, and im wanting to know more on the specs and what i can do to enhance the performance of my beast.

 

Ok, i know that i have the obdI comp chip, and i was told that it is un upgradeable, and that i cant get n e more performance from that. Is there n e thing else, just simple and easy to put on to help increase performance..

 

It would help out if you posted some specifics about your truck. Engine, tranny, XL, XLT, Lariat, etc.

 

1991 F150
5.0L 302
E40D
dual gas tanks,
XLT Lariat
114,000 miles,
Straight Piped after cat.

 

There is a ton of modifications you can do to those 5.0's. Here's my Stang if you want to have a look https://www.f150online.com/galleries....cfm?gnum=3326

It all depends how much you want to spend on it. My combo on my 5.0 looks like this.......
306CID, balanced bottom end
E303 Cam
Fully rollerised valvetrain
Typhoon upper and lower Intake
24# FMS injectors
C&L 76MM MAF
Edelbrock 70MM TB & EGR
Trick Flow Twisted Wedge heads, 2.02 in, 1.6 ex
MSD ignition
BBK Equal length shorties
Single chamber Flowmasters
2.5 inch exhaust
3.73's in da rear

So what do you want to know?

 

Ok, i know that there are a lot of upgrades and such for the mustangs, but i didnt know if that all applied to a truck engine as well. I am basically looking for small and minor changes to get the truck a little more horse. Nothing huge or dramatic, just a good noticable difference, and to make it so that i can race others on the road, and do very well at holding my own.

Basically, what are some quick and easy things to do???

 

Before I get too carried away, probably the easiest and least expensive thing tou can do is to swap out your rear gears. This alone will give you greatly added acceleration AND towing ability.

 

well i thought about that, and im not too worried about towing. Right now, i want more acceleration, not too much, im not wanting to get more tickets. Plus i wanna be able to keep the tires on the ground. I need to know more about the E40D tranny. Mine is shifting hard and acting more like a heavy duty tranny than n e thing else. Plus, i am going to y-pipe the exhaust and run straight off the cats. So, that will help a little. But, i would like to go 4.11 gears maybe, and do some modification to the engine.

 

What gears are you running right now? You will like the gear swap by far the best bang for the buck mod you will do.

 

right now it has the factory 8.8 3.55 gears. And im thinking the same as u. But i would like to make it a posi read end. I hate this limited slip. But, can u tell me n e thing about the E40
D???

 

Cant help you out there. My Mustang was a T-5. I dont know chit about the "E40"

 

See, i want to know more, cuz if it is more heavy duty, than that is really pulling down on the horse. So, idk, but thanks, i know more about what i wanna do now. Thanks

 

Whats idk?
I'm just a stupid canuck

 

You must not know n e thing...

 

I am guessing that if n e = any

that idk = I don't know...
