I like the Rhodes lifters. Like KK I have been using then since 1984. Kim
I think Rhoads are louder in a big block Chrysler, my buddy had them in a 440 Six Pack 4-speed GTX, they worked great but they hated the rattle so they pulled them....but did perform well.....like I said, they are quiet in my 340
If I were to run the rhoads lifters with this whiplash cam, I would only run them on the exhaust side.
Note for all reading this. Please LEARN FROM MY MISTAKE!!!! Do not use them to "tame" a big cam on a higher compression engine. That was a bad day for me. Detonated the crap out of one of my race engines and this was the end result. SHAT Happens.
How did you come to diagnose that failure due to the Rhoades lifters.
I've run them for years on many engines and for over 250,000 in an engine with no problems.
Are you sure that something else didn't cause that failure?
They are made to be used in severely OVER CAMMED engines to tame them down at low rpm, then make it come alive at high rpm. I have used them with success since that blowup with great results. I have a set of the VMAX lifters in a race engine running a solid cam. The torque curve was like a turbo Diesel, came on early and hung in there forever.
And I can tell you, they don't always pump all the way up at the higher rpm. Dynos are a wonderful tool for testing such things.
I've told members here that before.. but the old Rhoads Devotees just won't hear it.
You want to lose some lift and duration all over on your cam at all engine speeds the go ahead and use those snake oil lifters.
I am going to assume here that with Rhodes lifters it makes a big difference in what weight oil you use.
I would think that the heavier the oil the less benefit you get at idle and the quicker it pumps up at higher RPM and that thinner oils will take even longer to pump up.
I just put a set of them in the 340, haven't really run it yet, but I am running stock 10.5 forged pistons and a purple shaft 284 484 cam and a Melling High volume oil pump.
I plan on using 10/30 or 10/40 mobil 1 once it is broken in. if it is too noisy I may try 20/50.
What oil / pump combos have you guys used and have you noticed any difference ?
This is a great thread as I have been thinking about using the Rhoads with a 484 cam in my 340 that I am putting together for the Duster. My compression will not be anywhere near 11:1, more in the 9 - 10 range for pump gas. I just wanted to help with the idle and to increase the power band on the low end.
So BillGrissom used adjustable rockers with the Rhoads. Is that the ideal setup? I have two sets, one with the oil grooves on the shafts.
KrazyKuda, 66340Sedan, and Abodybomber, what rocker setup did you guys use?
And I must mention that I am convinced that Crackedback has very good points about how to properly tune the 484 cam in a 340.
You guys are great.
