Anybody know how much horsepower a stock 5.0 has and how many lb/fl of torque? Also, what are some cheap ways to get hosrepower without destroying the engine? 500-1,000 dollar range.
Thnx

 

A stock 302 was rated at 185 HP, I think!

Best thing to do...

1. Exhaust...high flow y-pipe, high flow convertor, 3" diameter cat-back, muffler of your choice...probably $300-$500

2. Advance timing to 13*-14*...free mod

3. Air intake kit/K&N filter...$100

4. Underdrive pulleys...$70

5. Install a set of gt-40p heads...best bang for the buck. Can be found for $600 brand new

Just remember the 5.0 is a darn near built proof engine but it is by no means a torque monster. Even with all of these "bolt ons" it will never produce as much low rpm torque as a stock 351w. Just remeber that your 5.0l makes it power above 2500 rpm.

 

what do you do if the thing spark knocks like crazy when you put the timing there?

 

BAck it off 2* and see what happens.

 

the 87-2 5.0L HO's were rated 225hp@4000 rpm and 300ft. lbs.@ 3000rpm. So I would guess youre non HO is easily 200 hp

 

yeah the HO's are... but the truck motor sounds closer to 185hp to me. the poor flowing intake and the weird TB and speed density are your enemies for hp. put a stock mustang efi upper on it, bigger tb, and convert her to mass air or recalibrate the speed density system and change your cam and add headers is the way to go.


oh yeah... get rid of your air pump and it will get you a few hp back....if you dont have emission testing....

 

92F150_XLT,

At best you have about 185 HP at the flywheel. The biggest thing with your year of truck is the speed density system. To get more out of the truck you will have to convert over to a Mass-Air controlled system. Summit has them Manual Transmission & Automatic Transmission. There are other places that sell the kits as well. Also you could probably ask around some junkyards and see if they have any wiring harnesses off a 1994 - 1995 F150 with the 5.0L or 5.8L engines. The only thing is if you get a 5.8L truck to donate from, you will not be able to use the computer from that truck but you might be able to make a quick trade at the junkyard for a 5.0L computer. This will allow the motor to better manage the use of the new parts that you wish to use later on. Right now, the speed density only tolerates a little change. If it gets pushed too far then the truck won't run right at all.

After that has been changed then the world is almost endless with the mods that you can do to the truck for more HP & TQ.

Another idea, although it doesn't add HP & TQ is to change your rear gears to 4.10's. This will launch the truck harder and faster on take-off. This can generally be done for about $300 - $600 depending upon where you get the parts and the labour to do the job.

Depends on the level of midification. Speed density is superior, but has limits.

However, now that we can tune the SD cars for bigger injectors, altered timing and fueling etc.... it would take a pretty good reason to switch. For $500 dollars I would get the HO cam, intake, and computer. For another $500 I would add on some GT40 heads, or port your E7's.

 

I have a 93 f150. Can I buy a chip for it? How much wil it cost? where do I get one. How mush does a chip help. Thanks

 

Buying a chip will not gain you enough hp to make up for the amount you spent on it. You could port your heads, get headers and bump up fuel pressure and net more hp. Once you get alot of flow improvements (more in and out) then a chip is required to re-calibrate the engine system.

 

For a little over $200, a superchips chip can net the following for the truck.

F150 5.0L - 1988-1996: +18HP & +24ft/lb

Talk to Mike Troyer on the Computer Chips section and he maybe even give him a call. He can tell you want you can do and the kind of money that you will need to get there. It all depends upon how much HP & TQ you want for the truck.

I still say port your heads and buy a mustang intake from a junker or used auto parts dealer. Get the same #s and have more throttle response...with the ported heads you would have to bump the fuel pressure up around 6-9psi over stock...which is free and works the same as a chip.

 

Thanks for the help.

 

Yes, but the chip can also eliminate the speed limiter, increase rev limiter if wanted and firm up the shifts on the tranny. Can't do any of that without the chip. The three best bang for your buck mods are the exhaust, air intake and chip. I have dropped just a shade over a 1/2 a second off of my truck with the below mods (see sig.) and that is when the truck is running lean and weighing in at close to 5000 lbs. Mike updated my chip after getting some dyno information for the truck and I hope to drop a little more off.

I have a 98 v8 triton stx will a 1995 5.0 f 150 motor fit on a swap I got the 4.6l in my 98
