I've read about people going as high as 6500-7000 stock rockers, not sure about cam profiles on them, David Barton has gone over 8k but I have no clue as to cam and rockers. I have a kid who works for me here that has a 06 magnum, 392 inch 5.7 , 4 in bore 3.9 stroke , Eagle heads runs a RLD- H5 cam Lift is 605/.611, stock rockers ,I've personally seen hit 7200 ,now he's running a set of PRW PQX steel rockers and is turning up to 7500. I think the crank is more of an issue then valve gear from some of the things I've read here on moparts

I deal with a shop that does a few Drag Pak engines. The original 6.1 cranks were cross drilled and that was the oiling issue. Just was wondering what was a common rpm for these engines with a hydraulic roller. Had no idea anyone besides T&D and Jesel were making rockers. Harland Sharp doesn't show them on their site. Thanks for the info.

What's the story on PRW rockers? Yes I would like to know that as well.

They don't look bad but they are $1169 at Jegs. Part # 3234513. Limited to 450 open pressure. I'd pay the 2k for Jesel Drag Pak or $2800 for T&D before I paid that for Chinese rockers.

I kept getting a 404 code when I went to their site. My magnum kid says the springs are what ever was on the Hughes heads he bought , he thinks they are 340/350 open they are a beehive spring.
