Id like to know the name of this shop..i worked with JE and Manley to design my motor...But your never make 250-270rwhp NA outa the OHV even built to the moon and back..trust me..I've built many of these motors and dyno about ever change...look up my thread (Rudy GM m90) because we definitely getting off track on this threadcustom work is my specialty.
i have a machine shop that will gladly make me fully forged everything for the 4.0, and i could even get a blueprinted billet block made up if i cared for it.
and yeah, **** tom, i built a 3.0 with his parts and ended up blowing the heads off around the 250hp mark...really dissapointed in that one. got another 3.0 after that, strapped a m90 to the top making 3psi of boost and a t3/t4 feding the m90 making 4psi, made 305hp at the crank and daily drove it for 4 years no problems. (behind a police SHO transmission)
im never going back to an automatic transmission again for a truck, just **** that.
i'll make my own thread when i get closer to getting the truck and starting the build
im not specifically looking for horsepower. i want alot of low end torque. i'll be rev limiting it to about 4200rpm's just to give it a fighting chance.
i want to make minimum 300lb-ft of torque out of it N/A
if i wanted to make power out of the ranger i could buy a built 5.3 from my neighbor for 650$, but personally i'd never put a chevy motor in a ford
i could buy a 5.4 lightning engine + trans off him for 2500 but i'd like to get some power out of the 4.0. realistically speaking if i got 250-270hp and 290-310lb-ft out of it N/A i'd be perfectly happy.

i made arrangements to buy the 4.8/5.3 off my neighbor.
its going to sit in his garage until its fully built.
im going to buy the engine, a massive precision turbocharger (i think its a 106mm?), a set of long tube headers,and the wiring harness he has for it.
then were going to buy aftermarket cams, oversized valves, port + polish the heads, deck the head, and just overall go in on that engine.
i'll make my own thread about it when i get off work.
anyone know if a t-56 will bolt up to the 4.8/5.3 vortec?
im also going to start looking around for a RV with a 460 in it, just as a backup incase i blow the 4.8/5.3
i want low-end torque, and thats where my t3/t4 comes in.
should spool in around 1300rpm, and im going to bypass it as soon as the precision spools in becuase that t3 cant flow anywhere NEAR where that precision does.
im only going to push maybe 15psi.
7psi from the t3, and 15 on the precision
get low end torque, and tons of high end if i needed it.
im not trying to make a racer, im just trying to adapt a very awesome, beast looking truck to my exact wants and needs.
i wont be EVER selling the ranger. it'll go in my garage when i get another truck, and it will sit aside my 67 mustang.
which the mustang also needs a restore. oops.
im thinking about buying a m35a2 and pillaging the massive heavy duty 6.72 geared axles from it. my neighbor would buy those for quite a pretty penny to use in his s10 dragster. (not going to spoil anything, but he's pushing close to 2500hp with a 5.3 and 60psi)
i will be tuning whatever engine i put in the ranger to run on atleast mid-grade fuel to prevent knock.
i know i could just go big and slap a 460 in it but man f**k that thing DRINKS, and it weighs alot.
if i could figure out how to work this site i'd post a picture of the ranger so you guys could see it.
dont mean to hijack a thread, just really a newbie when it comes to online forums.
and i have alot on my mind. big plans for my future haha
Stock is 9:1 i wouldnt go over 11:1 on pump 90+ gas!! Im going to the dyno soon,just got to put my new rearend in.but im shooting for 200+hp and over 300+tq.i would hope for 220 and 340 before the 150 shot
This was almost 8 years ago but yes I've far past that now..idk where you got 3500 rpms from tho..Did this ever happen? Gotta work some magic to make this kinda power at 3,500rpm. What do you recommend other than LOTS OF COMPRESSION to get this done?

I never broke 230rwhp NA nor has ANYONE i know of,think was like 226rwhp..that was with my 11:1, 422,head work blah blah built motor in the ranger before i stuck the supercharger on it...most 10:1 422 cam builds put down around 200-210 rwhp through a 5 speeds with light 26-28" tires.....and idk how the equation really works,ill have to find some of my dyno sheets and see if it really works that way..Horsepower = (Torque x RPM)/5252 . So 200hp must equal (300 x 3500)/5252 .
Forced induction would be the best way to go to make big power but I think he wants to do it NA, or did at some point.
Im not doubting the formula works,i just dont know how..id think it would hold more true on a engine dyno not rwhp dyno..i know if i do a pull in 3rd ill make more tq and less hp at said rpm but then do a pull in 4th and make more hp and less tq at said rpm..thats the correct formula for calculating power. im a mechanical + automotive engineer, i can back his claim up.
210hp would be perfectly fine by me. does the SOHC make more power? i can buy one of those and drop it in,in an afternoon assuming the wiring is the same.
the trucks got these ****ing 33" tires man, thats my only concern. their kinda big lol.
its 3.73:1 axle ratio and its a limited slip axle.
the trim model is XL supercab, and man let me tell you it looks ****ing beast.
attatched are some photographs.

Yea just dont see how it works and probably never will..lol i know on a engine dyno machine it makes what it makes..on a roller numbers can change drastically depending on how the dyno is setup or changes to the vehicle. ..if it makes 200hp it will never make more than that but tq it can make more depending on transmission and rear gears..It's not about one dyno measurement vs another. Just the mathematical relationship between torque and horsepower. Force (torque) times distance (RPM) creates power.
Hmm interesting, definitely makes little more sense now..i knew there was was to figure one or the other out just didnt know how and if they always held true..lolThe most helpful aspect of using this formula for me is it simplifies that you gotta have two things to make horsepower, torque and rpm. To make more power you gotta make more of one or both. A diesel typically makes lots more torque than hp due to being rpm limited. A Hayabusa makes lots-o hp from just 100ftlb of torque because of lots-o rpm. Ya gotta have one or the other. What's the old saying "Good, cheap, fast. Pick 2, the other will be determined for you." Same with Torque, Power, RPM. Pick 2, the other is a mathematical calculation. I used to struggle with accepting these equations until I realized that the word "power" is not just a word to describe something, it is a rate of work. Units of power are horsepower, watts....and probably some others I'm forgetting. Engineering defined these words many moons ago so we need to stop misusing them, LOL.
An electric motor can make dynamic and/or static torque, either spinning or not spinning. If you think about it, an internal combustion engine can't make any torque without rpm so it really only makes hp, torque is calculated.
Torque will equal HP at 5252rpm. Torque will never equal HP at any other rpm.
I lost like 65rwhp going from my ""street"" 33s and my 36x14.50 off road tires in my explorer with same motor,same trans and same 4.88 gears..that same motor in my ranger with 28" tires and 3.73 made almost 80rwhp more...i have dyno sheets somewhere,my numbers might be slightly off but closebigger tires will take more torque to turn,becuase their covering a greater distance. this is a variable that affects the overall total gear ratio (effective) and has to be taken into account on a dyno, if not taken into account then yes you will see losses.
the only way that you will get less HP to the ground by changing tires is if your losing alot of power to just heating the tires up,due to frictional losses from the tire deforming and rippling from weight and torque and lack of air pressure.
