Rhoads Lifters

[Pro74PW]

Has anybody used Rhoads lifters? What is your experience with them? Thanks

[rumblefish360]

I have. They help mello out a tuff cam for me. Drivablity improved as well as low end torque. There advertisement proved true for me.

[ehostler]

I've used them once and have nothing but good to say about them.

They mellowed out my idle and improved off idle throttle response. The particular engine that I put them in used to load up at idle and would flood itself out. After the Rhoads lifters, that problem was gone.

[Mr. Trans Am]

mega dittos on what the others said. Only dig is they are noisey as hell. Heard but don't really know the Cranes work *almost* as good but quiet.

[DartByU]

I haven't used Rhoads lifters but I have the Crane lifters in my Dart that work the same way but the Cranes are supposed to be quieter than Rhoads, I can't hear them at all, and they work really well for me, picked up the low end a little bit and helped the idle, I can idle at 700 RPM instead of 900 or better.

[6pakman]

work good for idle but noisey as all get out. guess thats why there anti pump up.

[JoeGrapes]

I've used The Crane lifters. I have a '70 440 Cuda with a MP 284/484 cam but the comp ratio is way to low, 8.6 to 1 for that cam so I put in the Crane's and gained 5 in. vachume about 15lbs of cyl. pressure and a smoother idle. I can't feel if it has more power down low when driving it on the street. But you know what, I'm still not happy with the power, so I'm doing what I should have done in the first place. Changing to higher comp. pistons to get the ratio up. The lifters work like they say but there're just a cruch. Your not going to get the "best of both world's" as they say.

[ehostler]

I didn't find the Rhoads lifters to be noisy. Then again, I was also running a loud exhaust, so I heard very little from under the hood.

[SubLime440]

I was going to use the Crane Version of them but decided to go with regular lifters with my Hughes Cam... and shave the heads for compression instead. I've got a brand new set sitting in my garage for a 440 if anyone is interested....

[Rug_Trucker]

I remember advising a friend to put them in his 70 351 Cleveland Cougar Eliminator. People would rev up at the light next to him and then back down when they heard the "tac-tac-tac!"

I thought recently I had read that the lifters bleed off and you loose lift on the top end? Anyone else heard this?

[HOLESHOT]

Both the new Crane and Comp lifters work well with only a slight loss of lift at low engine speeds.They work just like a regular lifter after 2500 rpm.I do agree if you need them you ve got the wrong setup in the first place.The noise factor is very low with these newer style lifters and I would consider them to be far better than Rhoads ever were.

You can read about the Rhoads lifters at this US Patent office webpage:

Skip on down past the lawyer-talk 'Claims' part and find the section that is labelled
"BACKGROUND AND SUMMARY OF THE INVENTION"

There is also some Rhoads info at:

I have a complete new-box-set of Rhoads lifters for AMC/Chrysler smallblocks that I would sell for $50.

I bought these from Summit for $78 in hopes that some of the internal parts would fit inside the body of the roller lifters presently used in the Magnum 360 but found I could not do this.

[Karl43]

I have been running Rhoades lifters for years now. It took a few years of research for me to get enough confidence to try them. Now I put them in all of my engines. You can run them with high lift cams and high pressure oil pumps without messing them up.

They work well, I hear better than the Crane's. I have heard criticism that they beat up the valve seats - not true. I have just rebuild an engine that I had them in and it made 200,000 miles. The engine did not have to be rebuilt because of lifter problems.

The Rhoades lifters bleed down at speeds below 3500 RPM and over 3500 RPM you get the full lift and duration from your cam. You have your cake and eat it too. They bleed down about 10-15° of duration and .025" of lift at idle. It gradually reaches full lift and duration by 3500.

I also bought a set once and found a low spot where the lifter body did not machine because of a void in the metal when the body was cast. I called Rhoades and described the "no clean up" condition to them and they sent me a new lifter immediately without asking me for the old one! In my experience, they also stand behind their product. They also helped me get a set made for my dad's 426 Hemi.

I recommend them

[amoparguy]

I've used them on a couple of seriously cammed BB Shivvies and they worked as advertised. They had a slight "tic" at idle but nothing objectionable. Can they be used on a Mopar with non-adjustable valvetrain? If so, how?

[Mr. Trans Am]

They go in just like any other lifter, no wild setup issues. I have an old mag here someplace that did a same day drag comparo and they cut quite a bit off the et and gave several inches more vac at idle in a BB chubby. The only downside is the affore mentioned noise. Has anybody ran the Crane's and these and these and can comment on performance and noise from each style?

[Karl43]

About the noise, they aren't that noisy to me. I've been able to get away telling people my 318 is an old 273 with solid lifters and they buy it!

The guy that recommended them to me used two hood insulation pads to help cover up the sound.

[curious]

is the noise really so horrendous that it d actually make you consider taking a cut in low end performance? what is the noise? is it like solid lifter clatter?

the hood pad really helps. my dads little grand am now sounds like it has solid lifters. maybe it does. just never noticed the sound unless the hood was up until he tore the pad off.

[ehostler]

In my opinion, they were not as noisy as solid lifters.

[Karl43]

In my opinion, they are not that noisey either.

[Duster_340]

I ran them in my "340". Way too noisy, annoyingly noisy in fact. Threw em away and installed the stock Mopar lifters and didn't notice any performance loss.
