Please help, lifter rattle won't go away

Gotchya. I guess it goes back to what I was sayin. If you're really gonna buils these motors, custom pushrods should be included.

I REALLY like the Rhoads VMax lifters. They are flippin badass. Read up on them. They adjust off the bottom. You can actually make a big difference in duration with them. You use feeler gauges to adjust them. Go on the Rhoads site and read about them. They are the VMax lifters, not the regular Rhoads. You can even run them bad boys on solid cams.

...and I wasnt worked up bad. I was just upset that I might not have got my point across and might not have helped you like I was trying to.

Here they are. And you need to get the kind with the full oil groove down the side. That splatters extra oil all over the lobes.

Rhoades are awesome. Ive never used the Vmax design. The regular lifter will have a ticking noise. Do the Vmax tick?

 

[RustyRatRod]

Yes. They sound like solids just like the regular Rhoads, but they produce much more power.

Good deal. Friend of mine had used the regular lifter with a 284/484 cam in his small block. What a difference in idle quality and low end

Oh God, I hate to bring it up if there are 2 different sets, sizes, whatever. But why on earth do they say that they fit all Mopar V8's except Hemi if they are different? Inquiring minds have to know.:blob1: The debate continues.

I thought I cleared that up. They DO fit all of them. What the industry did was move to the later style and used that as a blanket, even though the early style stuff is still available. Stupid as that sounds, that's the deal.

Hydraulic lifters have a wide range of travel in the plunger. My 451 has milled heads, and thin head gaskets. That makes the lifter plunger operate near the bottom of its travel in the lifter. I dont like that as they seem more likely to pump up at high RPMs. So I shimmed my rocker shafts .040". That made the plunger operate near the top of its travel. Better for drag strip use. But when you think about it, a .040 shim actually moves the lifter plunger up .080" . Thats .040 on the push rod side, and .040 on the valve stem side.

And everything works great like that. No probs at higher RPM S. Thats 6000 to 6200 tops. Mopar 509 cam and lifters, stock valve train.

I did some reading on the Roads lifters, they sound pretty good but I really don't want buy another set of pushrods and I don't like the ticking. Why do they tick? I read how to adjust them "weird" .020 from being bottomed out, you would think they wouldn't rattle being preloaded that much but I guess they obviously aren't normal lifters.

 

[RustyRatRod]

They dont have to tick. It depends on how you adjust them. But they tick because of the adjustment. The lifters don't pump all the way until about 4K RPM, hence the tick. Be careful which lifters you buy, because all the companies have a lifter similar to Rhoads. I got some Crane high intensity lifters once. They dont tick, but they work like Rhoads. I had a pretty choppy little cam and it idled smooth as hell. It really pissed me off.
