Steff, the 1237 PAC looks like what I need. Are you running a Gen 3 hemi? I have not been able to find a solid roller lifter to use. in my 392. I am using the 15820 Comp roller short travel hydraulic,. .060 travel. My first 392 uses the stock lifters and rockers with the Manley Nextek spring. It goes through at 7800 with no problem. I thought that using the Comp lifters with the T&D rockers would add stability to the combination, but something is not right. Like previously stated, the engine went into severe valve float at 7000 and hurt all 16 valves. I am trying to figure what component caused the problem. By the way, the T&D rockers are a piece of art. Thanks for helping. Dyno
There are no solid lifters available. Yes, I have a 425" G3, NA. In 2014-15, I originally shimmed a set of hydraulic roller lifters and had a solid roller cam made. I also use the T & D's. They worked well, but, after about 3 years using them, I had a lifter try to twist and hurt a lobe. For my new cam, I was able to score a set of barely used Jesel Dogbone Solid Roller Lifters and they are leaps and bounds nicer than stock ones. The nicest thing I love about them is that the pushrod cup is sunk into the lifter body just above the roller. It greatly reduces the side loading on the lifter body, compared to the stock lifter where the cup is at the top of the lifter. I shift mine at 8000-8200 regularly with no float issues.
