i need more power for low bucks any options

 

Whipple Charger (roots blower). Otherwise, a lot of mods to build usable torque. What is good for the Mustangs isn't always the best choice for a truck engine.

 

X2 alot of the mustang/car 4.6 parts ive notice are for very very high RPM the intake runners are alot shorter.

Were as the truck 4.6/5.0's are very tall for low end torque.

Same with cams alot of mustang cams ive read lookin for some for my truck dont even make power till 2,000-3,000RPM

The new 5.0's should make some good power with simple mods. CAI exhaust tuner. They are begging for new mufflers

 

I'm going to assume that you are asking about the 5.0 in the 1993 in your user header. With that in mind, here is my answer.

The 1993 is a speed density EFI system instead of a mass airflow system. This will limit how much you can and can not do to the engine as far as camshafts, etc.

The first thing I would recommend is the "Six Litre Tuneup". The basic idea of this is to improve the ignition system through using the following:

- Replace fuel filter and stock air filter (more on air filter later)
- An improved ignition coil (MSD or Accel)
- Improved cap and rotor (MSD or Accel)
- Better wires (Ford Racing, MSD, Accel, Taylor)
- Motorcraft plugs, gapped at .055". These engines hate anything other than Motorcraft or Autolite sparkplugs.
- Increase initital timing to 13 to 16 degrees BTDC with spout removed. Once you do this, listen CAREFULLY for any signs of ping on acceleration.

The best improvement after this is to replace the absolutely restrictive exhaust system from the manifolds back with a high flow catalytic converter (Walker/Dynomax #15022), along with a 2 1/2" exhaust system from the catalytic converter back. This will open up the major clog in performance.

Fortunately, the intake system is rather good. I would not recommend a K & N system for these engines, but would recommend a better breathing filter.

As for camshafts, I would not do anything to the camshaft itself, but I would seriously look into a set of 1.7:1 roller rockers to replace the stock 1.6:1 rockers. This will not affect the speed density system, but will give some improvement througout the RPM range.

One of the big improvements (both in cost and results) is to regear the differential(s) to improve acceleration. With a stock 29" tall tire, I would not hesitate to go with either a 3.73:1 or 4.10:1 gear ratio with the 5.0. This is something I would leave to professionals, but is the one thing that gives a great potential for improvement.

This should give you enough to go on for now. And you just may be surprised with how much improvement just the Six Litre Tuneup will do for your vehicle.

 

oh old school 302 stuff.

the biggest diff. my buddy did on his 302 bronco was to get an E-fan and to get the dual intake tubes that came on some later 302's with the dual Throttle bodys. he put mustang shortys on it no cat with a 2 1/2 Super 44 sounded good ran good too. but i think with a free flowing muffler like a dynomax or a maggie it would run alot better.

 

x2 on the efan!

 

I'm old I guess. I still consider efi 302/351 "New" stuff..

 

id take a 302/351/400/460 over these mod motors anyday.

just with the new 5.0 coming out wasnt sure witch one it was.

But i always recommend E-fans as a first mod lots of power cheap and easy to do.

The intake was pretty neat to i forget what 5.0's had the dual throttle bodys.

 

I like both engines. I'm also excited about the new engine line up my next truck will probably be one with a new 5.0 if they aren't junk like the 5.4 3v seems to be.

 

my exhaust was the best investment as far as power increase. i noticed much better bottom end with the bassani o/r y pipe, obx shorties, and well i have a 40 series flow but thats soon to change due to it being annoying driving down the road at 60mph. i didnt notice any difference with the my efan. didnt notice anything with my k&n intake. best thing you can do for the buck is tune it up with autolite copper cores a good quality set of wires, distributor cap, and rotor, msd coil and advance the timing to about 13* and make sure fuel and air filters are clean/new.
