Im using their lifters also, no problems here either after 2 seasons and they drop right in as stated above.
Is this a solid or hydraulic roller lifter.I take it that there is no block grinding.What about oil mods to the stock block 340.

I'm talking about the solid rollers, no grinding on OE 340 block, OE lifter bores.

For what it's worth, I've used his roller lifters for years, and for my money they are as good as anything out there.
His stuff tends to be pretty decent (remember, Chet Herbert is one of the oldest, most successful cam grinders ever), so I wouldn't be afraid to use it.

I used the Comp .394" CR lobes, sorry, didn't measure the base circle, just made sure the oil band in the lifter was not exposed, mild ported "J" heads, Herbert 1.500" IIRC double springs, factory 340 intake ported/plenum divider removed, JE flat tops.
Ran 10.71 @ 125 in a 3200 lb. Duster @ 3800 ft.DA last week at Fontana, Ca.

R5-P7 I tried sending you a PM but it was full.
I wanted to ask what the combination was and where you shift. That motor sounds real strong for a stock intake manifold.

I never did check the cyl pressure. I was using JE flat top 340 pistons at .010 in the hole with a 65cc head. My convertor flashed at 5400. It was an 8" tubro action for a 904. It ran 10.89 at almost 123 was it's best in a 3200 Dart. And that was shifting at 6800. When I shifted at 7400 it was in the 1/8 mile. And I only did it a few times. Forgot to turn on my airshifter. If you could I would collapse down one of your springs and if you know anybody that has a spring height checker you can check your installed height right on the motor. This is how I did mine.
