i have a 89 f150 with a 5.0L in it and i need more power. i have only done a few mods so far including a set of long tube headers no cats dual in let/ outlet muffler cold air, and a street/strip shift kit. i dont want to touch the pistons or drop in a 351 i want to be able to do most work by my self and spend as little as posible. i was thinking of using a set of trick flow or brodix heads, comp cams Ford 5.0 Xtreme Energy EFI XE274HR. edelbrock intake, bbk twin 61mm throttle body and 2500 stall with 411 posi. i have found lots of info on mustangs but none on trucks. also i would like to know some details of speed density and mass air systems. basically i want my truck to stomp camaros and mustangs and do 14 flat in the quarter.

 

Why would you ever want to do this? Here's the math; your truck is 1,000 lbs heavier, has truck driveline and has no weight (traction) on the rear end. You’ll never beat a car with a comparable engine. Have you ever seen a truck at a drag strip? After spending a ton of money, you’ll have a truck that’s about as fast as a standard truck with a big engine. What the point?

 

14 seconds is not going to be possible and still have it very streetable with a 302 in it.

First thing you will need to do is get the mass air conversion kit if you are going to put a cam in it. I believe its about $750 from Ford

 

Buy a lightning, end of story.

 

I'm not so sure just berating his question should be the first reaction...although I know you guys meant nothing by it.

Nothing is technically impossible. It would be possible to make your truck exactly what you wanted...but I highly doubt you want to spend the bucks needed. I wouldn't. And it would be just a shell of it's original by the time you finished.

A 14 is a very lofty goal on a 302 in a truck. If your truly set in wanting to keep the 302, and not at least strengthen the bottom end (for power adders), I don't know if there is any amount of parts that can get you there (I could be wrong...I am used to 351W and larger engines, so someone may need to correct me).

Was there a particular reason you didn't want to increase your displacement?

 

I'm sure it could be done with nitrous, a blower or turbo, but without going in to the engine and putting a crank, pistons and rods in it it aint going to happen

 

To make the kind of hp out of a 302 that you want without rebuilding the whole thing will be sort of difficult. If i was you, i would seriously look into a blower of some kind. (turbo or supercharger). I know there are "bold on" supercharger kits but i dont think anybody makes a complete turbo kit, so a turbo would be alot more fabrication work. Supercharger kits are quite expensive but if you add up all the little things your talking about i think they would equal out. I dont have any numbers to toss out with the supercharger so i dont know how much hp they would make and how fast they could make the truck go.
When my 302 finally gives out(hopefully not untill another 70,000mi), I think I'll look into a 347 stroker kit.

 

Like others have said, it's possible to get that kind of performance out of a 302, but with the attitude of, "spend as little as possible," you may as well give up now. It's not going to be cheap, but it IS within reach if you have the knowledge, the time, and the money. This forum can only help you with the knowledge, the rest is up to you.

 

ok maybe 14 seconds was a little high but i would like to have 350-400hp under the hood and not spend more than 5000 on it. i can do most work on it my self if i dont have to go into the bottem end so that will keep the cost down. ive been looking at some power packeges for mustangs and so far i fonf trickflow has a kit for 350hp 370tq, an edelbrock kit that does about the same or my own which consists of edelbrock intake, brodix heads, comp cams 5.0 Xtreme Energy EFI XE282HR Cam and pushrods etc, bbk 61mm throttle body, bigger fuel pump and injectors and a bigger mass air with the conversion. as far as traction i will be getting ladder bars and a set of slicks, its also a super cab so more weight is transfered to the rear. my truck weighs about 4180lbs and i will be removing the spare tire, back seat ect. to fee up some weight. according to a horsepower calculator found on geocities in order for my truck to do 14s i to have 300hp at the wheels and 390 at the flywheel. i would settle for around 15 tho

 

That kind of horsepower is still going to be hard to get with the money you want to spend and the work you want top do. Shoot for 300 and you should be able to get that with a mass air conversion and a few engine parts

 

also my dad owns a ford dealership here in melfort, sask and i can get ford parts for cost and he is also a mopac dealer so i get low prices on other things.

 

I am confused here. Someone correct me if I am wrong, but did he state anywhere why he didn't want to get a new engine. I am sure that you can find a 5.0L or bigger crate engine that will put out 400 hp for around $5000. For $5475.00 you can get a 342 ci crate engine with 400 hp from fordracing.com. Safe yourself all of the trouble and throw that in.

 

Does that come with a computer and all the sensors?

 

The crate engines that are sold on the website are carbuerated engines that are supposed to be direct replacements for Fox body Mustangs with a 5.0. Since he has a truck I am sure that this engine will sit right in there. Now depending on whether he has an automatic or manual transmission might effect the swap if he wants to stay with the stock transmission since it was designed to be hooked into a computer.

 

76cougar74100,
If you havent read it yet, go to the 221, 260, 289, 5.0/302, 5.8/351W V8 section of the forums under Performance, Engines and Troubleshooting. Find a post entitled "Went to see the engine builder today". Its a very long post about mustangGT221's experience with finding a motor for his f150. I would suggest reading the post for ideas, as there are several tossed around. If you have got 5000 to spend, i would look into a custom built engine, such as a 393, like mustangGT ended up getting. The post is definetly worth reading.
With the Ford Racing engines, most of them are designed to go into mustangs and have powerbands in the high rpm range. Most people say they arent well suited for trucks, or at least for any sort of towing. For your purposes, they may be worth a look into.
