Rhoads lifters - still available?
I cant seem to find anyone who has rhoads lifters for Pontiacs. Are they still in business?

I just got a set from Rhodes in January.
It took a few phone calls to get ahold of them. They were "in stock" when I ordered them and received them in a week or two, Good luck

I was wondering why only the Pontiac communities embrace Rhoads lifters nowadays. I have read about anyone using them in a build in years. When I went to Westech to have my engine dynoed he said oh yeah that's a Pontiac thing.....or that was a Ken Crocie thing, nobody else runs them. What are your thoughts and are they still relevant in today's cams?

i run them in pontiacs, and had especially good luck in them in over cammed 454 chevys, since a big chevy will turn 6500-7k, i9 put a big cam in and can still run a/c pdb, using rhoades

I picked up a set for a possible 455 build. Cliff has said that a 9.5-10:1 CR 455 is a great match for a Crower 60919(very close to an 041 cam) and Rhoads. He went on to say it gave up very little compared to a hyd roller that he dynoed. So I suppose with the proper cam selection and Rhoads you could have similar performance to a roller, for less coin.

Btw.... No one seemed enraged when all the other lifter companies tried to copy the Rhoades lifters like they are about SM. |

Rollers became more and more prevalent in the aftermarket late 80's early 90's and most hot rodders were simply going that direction, that's one reason. Others would complain about the noise of the original rhoads, as many do here, that's another reason.
Quite a few of the die hard Pontiac guys I was around never ran rhoads and didn't show much interest in them. These days since they use Johnson lifters to start with and also offer a super lube option makes them more attractive in my eyes. Plus new versions (technically been out for years now) can be lashed pretty tight to a point they are pretty quiet but of course that's a trade off as it diminishes what they were designed for. |

https://patents.google.com/patent/US3304925A/en On the V series, the way they are shimmed off the bottom the lash gets rid of the hydraulic cushion most hyd lifters have. Most HFT lifters for high rpms the lifters have to be set at the top of the travel, they still will collapse some though. The original collapse a lot also unless you bottom them out. On the street I like the V series Rhoad’s with set the lash tight. Most of the bottom end and vacuum gains come early when the profile is slower which happens most at the low lifts. With the lash set tight they can be quieter than a normal lifter, and rev like a SFT. That is the apps I usually use them for. I usually set them at .006” to .008” lash. |

Yeah Jay, oil is always a weird subject with people. Someone on the internet always says this or that is better yet almost no one even sends off a sample to see what their oil is doing.
I will say this, plenty of oil testing done with very expensive equipment that has shown too little and too much zddp can be harmful. What's the right amount? Only an oil analysis will tell you what your engine likes. The other thing to watch for is the lighter weight oils. Another weird subject with people that isn't cut and dry. Everyone wants a lightweight oil but you have to be careful as the API ratings don't allow as much zddp in these 5-30 and 10-30 oils. Some have more than others but the API puts a cap on the amount allowed in the light weight oils, some dont even have 700 ppm. Not to mention the zddp today is different than it was just 15 years ago as several regulations were passed to make it more compliant with cat converters, but that's another subject. How much do you want? Again you need an oil analysis to tell you that, every engine is a bit different. |

I am sure that Rhoads does not make a living off of just Pontiac lifters!
People who do not use them and have over Cam’ed motors are some of the other brands that we blow into the weeds with our motors.

One thing that surprises me is Rhoads does not offer a lifter for the LS Series - had they it may be an option for gen V builds that delete the DOD.

Gaining 3” to 5” of vacuum is pretty huge when you have a bigger cam and need to pass a sniff test. The down side is if your concerned with lifter noise, with aluminum heads they are not the easiest to set, they much louder once the engine is hot. Aluminum headed Pontiac’s can be loud with the V series flat tappet lifters also once hot. People set them at .020” cold like the Rhoads instructions say then end up running .026” to .030” hot. They get loud fast after .020”. Probably adds some abuse on the valve guides too. Last edited by Jay S; 04-25-2024 at 10:52 PM. |

Nothing but Love for Rhoads lifters!! I've been running their V-Max lifters with the biggest Lunati Voodoo HFT cam for years. It's been a great bracket and index combo and has certainly surprised/upset many "faster" cars no prep heads up racing as well.

They are available and are for the cam that you want, but that cam iss 10-15 degrees bigger than you think you should buy. The Rhoads are magic in my opinion. I put them in everything I can. Including the rollers. Even put a set of rollers in a 393 stroker 318 Mopar recently. The sound is similar to a perfectly lashed solid cam. I know they go to 7100rpm with enough spring. Buy the cam that is "too big" install the Rhoads and enjoy. BTW the Pontiac community is a fraction of total Rhoads sales.

What’s also interesting to me since I’m still on the fence about what HFT cam & lifters to purchase is that you never hear about a flat tappet cam failure with Rhoads lifters but that might be because not many folks use them now a days.
