roughly 148hp at the fly... about 125ish at the wheels.

estimating gains is a real tough thing to do, as every application is different, but i'd say with those mods, expect to gain around 15-20hp.

Ok thanks what else could I do it? I am hoping to get 200hp to the rear wheels out of it. Is it possible?

200hp? wow, that would be VERY tough. if youre looking to get 200hp at the wheels N/A, you'll be looking at a FULL engine rebuild. now with a power adder like the whipple supercharger or nitrous, you can get close to 200hp much easier.

thats a much more attainable goal :o) in addition to the mods you have listed, add roller rockers and maybe regear up to 4:10's or 4:56's (if youre currently running 3:73's) and you should be damn close.

I'll agree with Brian. My automatic with underdog pulley got me to 130 to the rear from a 121 starting Point. 8 -10 for x cal II and approx 10 for roller rockers should get you real close. Those three seem to be independant of each other so 1+1+1 should equal 3.

I don't give too much credit to intake and exhaust. It seems they add the HP in such a limited RPM range that 10 for an exhaust and 5 for an intake won't add up to 15. That would be 1+1 does not equal 2.

Dynos tell all though, so its all speculation until its done.

Thanks guys. I am hoping for it to have some more get up and go that is all. How hard would it be to do a 4.0 swap in it once the 3.0 goes? Thanks again for all the help.

Going from my 3.55s to 4.10s with my L/S made a good difference. Also Intake, Headerback exhaust on my truck it runs noticeably better too...

Well how hard is it to stuff a 5.0 motor in there with a tranny that would hold up as well as the rear end? I am looking to be pushing around 280 to the rear wheels.

Swapping out his gears wont give him more horsepower, they will make the truck quicker, making it feel like an animal on acceleration(compared to stock atleast). Going 4.10's or 4.56's would actually make it dyno lower than a similarly modded truck with stock gears, but they are still one of the best mods for any RWD application.

I am probably going to have to go with 4.10 gears due do the fact I am putting 33's on my truck.

instead of doing all these expensive things, just either sell the truck buy another one with a bigger motor, or drive that truck into the ground and save up money to buy another one. the 3.0 isnt that bad. if you knew the truck had a 3.0 in it why did you get it?

I didn't get to choose the truck. I needed a truck that wouldn't kill me in gas. I have a 1969 GMC K2500 that I drove around with a 454. Gas was killing me 100 bucks every week so I parked it then my dad and me went looking for trucks. At the time I didn't know 3.0 or 4.0. I needed a truck that I could haul my quad with was good on gas and could go off-roading with it. I really wish I could have gotten a different one but you cant always get what you want. So I am just trying to make the best out of it with what I got. See I am going to buy a camburg 5.5 system for the front and rear. I just want to have the power to use the truck and suspension. So either a)built the 3.0 and have hopefully 180-200 horsepower to the ground or B) Drop in a ford v8(probably the 302 as it seems the easiest). How much would a complete V8 and trans with the gears in it that wouldnt explod cost?

if it was me, id do 2 upgrades, the lower gears and maybe a chip. that will give you enough power for offroading and hauling the quad, and the chip can do a lot, im sure a lot of people have a chip. but yea its cool man, its true, we all cant get what we want.

Yeah I wanna do the gears with my 33's so it isnt a dog. I am just trying to make some power to still use the suspension kit for what it is meant for. I am just trying to decide is it really worth the money to make the 3.0L have 175 rear wheel horsepower or leave it stock. What are some mods that will get me there the underdrive pulley,chip, and roller rockers should get me close to 150 according to graniteguy then all I need is 25 more hp and I will be set!

Im in the same boat you are desert, my truck was picked out by my parents, and was sitting in the driveway after a day of fishing a few years ago. Ive been thinking over the last few years, of ways to make it faster, but realized, there are a limited amount of performance parts for the 3.0, and even if I were to buy all the parts to help it, it would be faster, yes, but I would still want it faster. A 302(5.0l) swap is in my opinion a easy swap to do. you don't have to do much modding to the engine bay. you have it a little easier being a 2wd(Im assuming with the camburg lift) as you wont have to find a transfer case and then 2 driveshafts. The reason im looking at a 302 vs. modding the 3.0, is the range of parts available for them. Either way, its going to be expensive. I got on summit the other day, and picked out every performance part minus a supercharger, and it was around $2600. I beleive you can find a pretty good motor and tranny for not much more then that. consider one out of an explorer, as they seem to be the easiest to swap. but for some words of advice, unless youve got the money just sitting around, just drive what you've got until the motor goes. my engine has 144k miles on it, and still running strong,my 302 only is going to come when my engine goes. Just save up the money for it, and by the time your motor goes, think about it again whether you want a new motor, and probly by then your saved money can be used on a whole new truck. oh and another that ive learned the hard way, off-roading is fun, I love it, but if you plan on doing hard wheeling, have one truck for your daily driver, then go buy something like your old truck for a trail truck, my truck sat for weeks, while I was saving up the money to fix the rear end and transmission that went out on me on the trail. and being young with no ride, sucks.

Yes I am keeping that in mind, if I wheel it too hard it will break so I plan on building it slowly. I would like to do a 302 swap but I would like to also keep my a/c and such. And also I want the motor and trans to be new as well. I will probably just install the underdrive pulley,exhuast,intake,chip,and roller's and call it done and drive it for what it is. Then once it goes cram a 302 in it and be done with it. What to do what to do....LOL.

Desert Racer. In order to get close to 200 hp without forced induction, check out this website. http://rogueperformance.com/RogueRanger.html That should give you a good idea of what is involved..

Although.. forced induction is a very easy way to break the 200hp mark :)
.. just not easy on the wallet.
