Got-LT1

I just read a tech question in a magazine that talked about Rhoads lifters. It says they have a "leakdown" at low rpm but operate normally in upper rpms. This is supposed to reduce the lope at idle, creating more vaccum and improve milage. At higher rpms they operate better than a normal lifter. the only side-effect is that it makes a cam sound like a solid-lifter (Would love for my car to sound like that). Are they any good and do they make them for an LT1? I might use them when I do my "custom" CC306.

They sound cool, but they will give your knock sensor fits!

Well im doing a search like people ask.... Has any one used these lifters on the LT1 or when doing a cam swap? I figured that there better then stock and couldn't be as bad as the comp R lifters. Summit has them for 99.95 for 16

In the catalog it says "They give less duration and lift at idle, for up to 25% more low-end torque and economy, and restore full action for top-end horsepower."

That has to be for flat tappets and we usually use roller lifters.

Yep, unless they've come out with a roller recently then they're talking flat tappet lifters.

on the rhoads lifters website I do believe that they are available for a roller chevy motor. a friend of mine has a 240/244 .530/.540 cam in a carbed 383 stroker motor and it sounds really mellow with these lifters. definately helps with vacuum

Well my goal isnt to make it sound mellow im just looking for something better then stock and not as bad as comp R's where i gonna have to worry about clips breaking or anything. Do you know how there performing in his set-up.

I do believe they make the rollers BUT they are going to cost a lot more than $99.

I inquired about these after reading the article in Hot Rod a few monthes ago. This is the answer I got. "We do make Rhoads VMax Lifters for the LT1 engine. If your engine uses OE roller lifters, the part number would be RL-1158X. If you have flat tappets, the part number is RL-8178X. You can either order on our web site, or call us at 520-229-9375."
On their website its $239 for a set.http://www.rhoadslifters.com/sc/agor...Roller-Lifters

I am interested to know how well they work. I would like a little more low end torque out of the 306 cam I have installed.
