hello i have been reading on ranger roller cams on this site but it is a little fuzzy i have a 79 2.3 that is torn apart right now so i was browsing the junkyard and found a ranger do all rangers have roller cams?? and can i put on in on my 2.3 head with the roller lifters and ect. or do i need to do any modifycations??

Not all Rangers hhave roller cams,I have one from a 91.You will need the cam,roller followers and lifters.It will fit all 2.3 heads.
The question is why. That's a few bucks for not much, if any, power gain. The big boost turbo guys use them to reduce friction, that's all. The cams are basicly stock n/a ones. There are good aftermarket performance ones out there to pep-up a n/a engine.

Hey Bill,
OK,
Lets say that a 2.3 is putting out 80 HP and the lower friction of the roller cam allows the engine to make 8 more HP! Thats 10% MORE!!!!!
I do not know how much more power the roller cam makes.
BUT More is MORE even if it's only 4 HP it is still 5% MORE.
5% is a heck of alot more than say... Using synthetic oil to make more power.
You guys know who you are that have tried it!!!!! ;D
I would take a roller cam over a slider any day.
The roller cam is like ZERO wear ZERO wories>>>>>

Hey Bill,
Please elaborate on the turbo guy's not using a performance cam.
This is something I have nver heard about.
from pintony
i was just wondering about if it would work i cant find a good used slider cam bc at the junkyard they are all pretty fried so i heard about the wear or almost non on a roller cam and theres a ranger sitting there so why not i wasnt trying to get horse power
it was pretty bad enough that i have to replace it it looks like some one ran it out of oil its pretty scored up so i thougt mabey a little less friction
The Ranger roller is a good cam.It is basically a stock cam with the same specs as a slider,but the ramps are a little different due to contact area.HP gain due to less friction will be minimal,you will gain some HP but not enough to feel.There are lots of performance roller cams available for the 2.3,but they are expensive.If you are wanting to install it just for reliability and you can pick one up complete for a good price go for it.
I have ran both the Ranger roller and an Esslinger Roller in my cars. The Ranger roller worked well on my stock 84 SVO motor. Actually, It was not the cam that failed but a rod out the side of the block. My Esslinger Roller is a 585 lift X 234 dur. at .050. That cam worked ( is working ) well but I could most certianly use about 600 lift X 260 dur. roller. AnyHow, Of the guys I hang with they would say most any roller on a turbo car is a good thing.
Also, we comrades that live in the Peoples Republik of California and have to maintain the government mandated smog systems, adding the roller cams makes sense. Anything that can be done to reduce friction in the engine that would free up any horsepower is always welcome! The engine may not always produce MORE horsepower, but it's using LESS horsepower to operate and overcome the friction in the valve train with a roller cam!
I agree with 79Pannel!!!!!
I have one in the new 2300 I built for my car. I have noticed no power gains but maybe alittle better low end torque They work with stock Pinto lifters also. I would rather have a performance non-roller than this stock ranger one. Best thinf about them wear wise, is that they are billet.
Hey Fast, try an adjustable cam pully.
I have tried one, the ford motorsports multi-doweled one. Made little or no difference.. I do have a question for you all. The book says to set initial timing @ 20 degrees BTDC, at least for my automatic. When I do this, it pre-detentes, (pings), under light accel. I have checked and made sure the vacuum hose was on the correct carb. port, made sure the centrifugal advance was working right, everything I think is right but it still does this. I have gone to setting timing @ 16 BTDC with no vacuum advance and it runs pretty good, but I know it would have better part-throttle power with the vacuum hooked up. Anyone had this problem?? Even running higher grade gas made no difference, except to my wallet!!! Does the Ranger cam need a different timing set-up to run right? Is there a way to limit the amount of advance the vacuum diaphragm gives?? I know the older Ford v-8s (like the 390) had a screw inside where the hose connects, that could be adjusted with an Allen wrench.. Any thoughts???
not to sure the exact year tht they started doing the roller cams in the 4cyls but i know that a 88 ranger 2.3 has it
also i know that in 85 or 86 they started putting roller cams into small block ford v8s (in the fullsize cars like grand marquis, lincoln, ltd, and crown vics) and it is almost imposible to kill one i ran one in 10 or 11 demoes much less around the farm playing the motor lasted for 2 cars and 4 years then i pulled it and put it in my 74 f100 and then a week later the tranny went out. the motor is so loose it isnt funny i didnt put new bearings or rings into it becouse i didnt want to see how bad it was LOL
