Ok here is what I want to know? what will converting to Full rollers do my truck if I switched to them? I'm talking exhaust, intake, power, speed everything? this is my question for anybody who has done this to their ranger. I haven't really done hardly enough with valvetrain components on rangers to know for sure. I've put headers on some peoples rangers exhausts, engine swaps but no one has come to me with this type of mod yet. any help on this woul'd be useful. Thanks.

 

Go to Wayne's (graniteguy) website Underdog Performance. He sells Roller Rockers for 3.0's or Talk to Fredness, the 3.0 guru.

 

Done in place, heads stay on the block.
~8HP at the wheels, reduced heat, reduced noise, increased MPG, reduced wear, longer oil life. Pretty sweet. They rev like nobody's business too.

Not for the faint of heart, it requires running a tap in all 12 holes, using lock tite to secure the studs and then adjusting the valvetrain. On high mileage engines (or a collapsed lifter) this can be tricky. I've done at least 6 sets and one of them was with NEW lifters - piece of cake.

 

Can you elaborate please?

This too please. What kind of adjustments need to be made?

 

Well I kindly figured that machining would come into play. Mostly the only valve/head jobs were done in advance and usually when u order these parts they mainly become plug and play type assembly. Most maching I ever did was crankshafts and camshafts. As far as doing it, NOPE i aint doing it because basicly if ur going to do that u just as well rebuild the motor at that point. I just wanted to know what it would do performance wise in a V6 engine. Mostly 4 cylinders (tuners) and V8's are usually what I end up working on. I do know how they work and a little about porting but the tolerances have to be EXACT and alot of flow testing and time are involved. Something I don't have alot of these days is time. All i am going to do for right now is put a set of liberator All terrain Tires from Walmart (stock size is P235/75/R15) which they have in my size and that is it for now.

 

Killer Thanks pal. U are talking rough idle right? Mine is pretty nasty now. The stereo is useless. U can't hear it. That badass terminator muffler (1 into
2) 6 inches behind cab and nothing else, it drowns out OZZY Osbourne, Metallica, and Megadeth FULL BLAST. Does directions come with the set? More info on this would be killer. I aint changing to a Flowmaster EVER AGAIN. I put an American Thunder off the header and a slant cut tip off the muffler. My uncle said it sounded like a hemi with a bad exhaust and he heard me 2 blocks away and it got me pulled over 9 times in a week. The Judge dropped it. Good thing I kept the ticket I got the first time or I would've had 8 more just like it. But what type of Idle are we talking? Rough, Choppy?

 

I thank all of you for any info on this matter. The reason I asked is some cat is wanting me to "DR. Frankenstien" his 02 Ranger Edge ext. Cab 3.0 V6 this weekend. It does need to be retuned, and looked at and Like I said Not much is available for his engine and mine. Turbochargers have come up, but what he doesn't know is that major,major amounts of $$$$$$ is going to be involved plus my fee for doing this as well. The turbochargers are OUT OF THE QUESTION. TOO MUCH PRESSUREIZED AIR FOR HIS ENGINE TO HANDLE. NOS is bad news in general that is out too. I also don't know what he wants to spend to get his Danger Ranger Freaked out. If it's only a couple of hundred bucks I'll just send him to an exhaust shop and not charge him for it. If it is a couple of thousand however, urs truly will be doing a V8 swap. I will let U all know for sure this weekend. When faced with a project like this U explore ALL options no questions asked if U want to do the job right. Thanks again everyone for ur help in this matter. It is extremely appreciated. This cat better be ready to go rent a car while I work on this (unless he does not want to spend alot of money of course).

 

I talked to my dad about rockers, He said that way he use to get rockers the right tightness is just to star the engine up and as its idling just tighten it down until it had no more play in it. I've never heard anyone do this before so i wanted to know how bad of an idea it was.

 

im shocked ford is not using roller lifters and hydro push rods.

 

well the project didn't make it. The numbers he was asking for the amount of money he was willing to pay, was and is impossible. he was only willing to put in around $150.00 measly dollars and that was all, yet he wanted NOS,Turbochargers, custom intake and exhaust manifold, custom exhaust the whole 9 yards. His wife came in and saw the list of crap he wanted and she asked him what he was willing to pay then started to laugh at him uncontrollably and called him an idiot. His wife knew more than he did and she can't tell the difference between V6 and a V8. That told me that he has been watching too many TV shows and Movies over the weekend. For that price all he can really do is change mufflers and that is it. His Ranger was in really really bad shape. The chassis was bent to the extreme, and it didn't have a V6 it had an inline 4 and it wasn't an extended cab either.the tires were underinflated to say the least. He said he tried to adjust the tire pressure for better fuel economy (myself snickering trying not ot laugh). If i get another cat like this i'm just going to quit tuning and modifying everyone elses and just do my own crap. This guy was the poster child for idiots. This guy gives new meaning to the word Joke to say the least. He didn't even know what he was driving. My truck made nearly 2 of his.

 

Dayo J, i hate to inform u but u are indeed sadly mistaken. U see I use to think NOS was pretty kool until I saw first hand what it can do to an engine. "it fries" the o ring seals, head gaskets, Piston rings and has been known to burn holes in blocks the size of ur fist. Plus I had one do a little dance in my face. I got lucky not having anymore scars especially on my face. And here's the scary part. It didn't happen right away either and it was installed by the NOS company itself NOS a holley performance brand. Even he didn't like it. And those guys do R&D 24/7 even in their sleep. After that I quit racing at friday night street fights at Bristol Motor speedway where u can bring what ever u want, sign an insurance waiver and bring a helment U can race. So yeah I hate N.O.S. but I know what it can do to an engine first hand.
So trust my personal exp. on this matter. And yes I do work on cars and tuning in my personal time as a hobby. And my dear please watch whom u call idiots. The research and in lab and on track tests have proven that NOS is all around Bad news "in the long run" if it doesn't blow up in ur face. Plus why do u think that it is not mentioned in TV shows on speed, TLC, and spike TV's weekend shows. NOPI TUNER is the only one that pushes it and that show is so old it's scary. According to speed tv, they're about to be kicked off if they don't come up with new shows and different cars. According to NOPI the only car to tune is the new chevy cobalt which is a bad copy of the neon and civic basicly.

 

Ok here's what I think and know. Yes I spent roughly 8 months in a hospital so yeah I know ur wrong. B i hit 25 over 7 years ago, and C ur calling an R&D developer an idiot that was and is over Holley's sponsorship program idiots!? U stupid broad. U didn't read very well did u. B4 u call guys Like NASCAR, HOLLY, And a few others idiots u might want to read a little more into it. Besides if anyone around here has any credibility problems it u. Let's test ur knowledge Dayno J.

 

The lifters are rollers at the cam, but the rockers are not.

 

Yes I know. a 218 degree flat tappet cam with roller lifters sounds good, extremely rough idle, and has killer performance.

 

I figured you did. I was responding to the other guy who expressed surprise that there wasn't anything "rolling" in the valve train, lol.

 

Ok kool. Thanks pal. he failed his other tech question too. I asked if u can run 87 octane with 11.0:1 compression. He called me an idiot and I responded and noted that he failed. Advance the timing 45 degrees, and change to low impedance injectors and u can run on 87 octane gasoline. Where this cat claimed he got his certifacation I wouldn't want to know.

 

I did'nt know there was going to be a tuning test or I would have studied.Nitrous is only as dangerous as the user.It's all common sense knowing how much the motor can handle and having the right tune.And yes I speak from experience.Sorry for your hospital stay,but Nitrous does not jump out and attack.
You did something wrong.

 

wow... that kid got owned by you D in all of his attempts.

 

Another one bites the dust. Like the one with the 14" wheels and 11.50 tires......bit the dust.

I didn't want to see him go....i wanted to know his next thread.
