im 17 no money to spare gas and truck use it all so i wanna know what kind of bolt on power can u get out of a 300 i want to do gears trany and cam shaft but no time or money yet what does the bolt ons cost

 

I think most folks here will say that you can get a noticable improvement, though nothing spectacular, by installing a free flowing muffler. The factory muffler is a big cork. Besides, it will sound a lot better.

What year is your truck? Manual or automatic? Miles?

Depending on the gearing, you might be able to get an entire rear axle assembly at the wrecking yard for a decent price. I got a 3.08 geared assembly, even had brakes on it, for $250. I suspect lower gears (higher number) will cost a bit more and surely limited slip will cost more.

 

its an 83 f-100 explorer 2x4 automatic 3 speed

 

No money? How are these parts going to materialize?

17? Focus on school, take a typing class, get some job training and THEN you can throw money away.

You've got all the power you can handle as it is.

 

x2 listen to his wisdom

 

Though it may be good advice......were you never 17???
I'm not even gonna touch the "all the power you can handle" bit

You could try just being helpful....

Just my 2 cents

 

Sounds like a nice truck. I once had an 84 F150. I wonder what rear end gear you have. Do you know?

Also with a 3 speed auto, you do have the torque multiplication function of the torque converter, which effectively gives you a lower gearing on take off, so in a sense, three speeds.

I would guess that the tranny is fairly simple being a 3 speed and hopefully that also means strong.

If your rear gear it to high (My 84 was manual with OD and had something like a 2.47 rear gear, what a dog), the axle exchange would be a good deal, so long as you don't do a lot of highway driving. You could buy the assembly from a wrecking yard and I would think sell the one you pull out of the truck to make up some of the cost.

 

I was 17 for a whole year. I was distracted by other things including cars at that age. Read this mans post and ask yourself what he really needs help with.

 

 

I realize what you're saying. I did agree it was good advice.
I think he was looking for some cheap alternatives to what he couldn't afford.
Of course any way you slice it....an increase in horsepower means a decrease in cash.
I've noticed alot of improvements on this forum for the 300 I-6....but they all seem to be for the carbed version. Still looking though.

 

hmm where did the rest of my post go haha.

look at my siggy for EFI mods

 

I love the 92-96 f series...I will likely keep this truck as a work truck and not do too much to it, though I would like it to sound a little better.
I do blieve I will pick up another this summer. possibly a little stepside with a v8.
Did they make a supercab stepside??
So other than upgraded coil and wires, you only installed headers and a cam.
No rockers?
What impovements did this give you?

 

rockers need to be machined down x amount. SilverStreak did that and saw minimal gain. only other thing to be done is headwork. i had a spare head but i found a large crack so i scrapped it. i also plan to add an electric fan and maybe port match my upper and lower intakes for the hell of it, if there is any size discrepency. i may even try a 302 throttle body on my spare intake, hehe.

considering im pulling 33" mudders with stock gears and a built slushbox it pull hard up to 100.

they did make a stepside in an extended cab configuration.

 

On a mostly stock EFI 300 headers are almost overkill.

For the same money, or less, pull the EFI exhaust manafolds and cleanup out any casting flash and carbon buildup and your good. Replace the two stock cats with a single 2 into 1 universal cat. replace the stock muffler with a freer flowing one, and maybe upgrade from 2.25" to 2.5" pipes (they don't have to be stainless steel).

While your at it replace the O2 sensor(s) as well. When they carbon up they can sent incorrect signals to the computer.

Even though I've done it as well, the hotter coil isn't really needed in a mostly stock engine either. But, you should upgrade the TFI module at the same time for better spark control. The stock spec sparkplugs are just fine with either the Crane coil that Opti recommends or the Accel Super coil that I used, but you do need to open the gap to .050 to .055 to take advantage of the hotter spark.

If you choose to replace the cam replace the timing gears with metal ones at the same time. Cloyes is the only company, that I've found, that makes a set any more. This gear set ahs three different keyways for installation (5* retard/straitup/5* advance). If your not in a state with a require emission test install at straight up for best all around gains.

 

dyno says otherwise on the headers
