Anyone have any experience with Rhoads lifters in the Olds 330? I bought a 66 Cutlass and the guy who had the car put the W-31 cam in it. The Duration is 308! Way too much for the street. I was thinking that the Rhoads lifters might make it more streetable in the lower rpms while still keeping the high rpm pull that the motor currently has.

Any advice?

 

nobody chiming in, well here goes nothing rhodes lifters are built for real lumpy cams it smooths them out so you get streeability on the low end and lots of power on the top end it might even improve your vacume as well

Not might it does. I run them in the 468 BBO in my 80 GMC, in the 455 in my 1965 442 & have had one other engine with them. I like them but they are not for every engine or engine builder.

 

The O.P. who asked this question in Feb 2007 hasn't logged into this site since May 2008. Hopefully he's fixed his cam problem by now...

 

yep i suppose

 

Well, while we're here, and since the post is 8 years old, maybe we can hijack it a little. Let's talk about the Rhoads lifters a bit. How do they work? Are they still being made? What kind of reduction can be expected? I want to run a lumpier cam in my car as well, but I'm also concerned about off-idle manners and such. What is the general consensus on these?

 

Rhodes lifters have a controlled "leakdown". The lifter actually bleeds off some oil to reduce the valve lift and duration. This is most pronounced at lower engine speeds.
As engine speed increases , there is less time for the lifter to bleed down. So lift and duration come up to "normal" specs.
Yes, Rhodes lifters is still in business;

Crane Cams also offers a similar lifter that they call "Hi-Vac"
