I'm running a solid roller in my 451. The specs are 253/263 @ .050, .610/.610 lift after lash. I believe my spring pressure is in the neigborhood of 550 lbs/in. Luckily this rocker just broke at an idle and the car was shut off immediately. What are you guys using? I need a new set of 1.60 ratio rockers. I like the sound of the Comp Pro-Magnums, but they don't offer them in a 1.60 ratio.

The Comps would need bronze bushings added to hold up with the spring pressure you are running. I run them and like them but over around 450 lb/.6" lift they can gall without the bushings.

So does everywhere charge $125 more for the 1.6 Harland Sharps compared to the 1.5's? Mancini, Summit and Jegs all do. Any links to sites that offer T&D or Jesel? I have no idea what $$$ those cost. Thanks!

I have the blue Mopar Performance ones that are made by Crane. I broke one this season at just under 7000 RPM's in the lights on 1/4 mile. Mine broke at the same spot, looks identical to yours. I replaced mine with a spare on, and replaced the mangled up push rod, so far so good.

Brian, that looks real familiar! I had a spare rocker around, slapped her on and went racing yesterday. I'm just worried it will keep happening. My car is driven on the street a decent amount.

Call Harland direct and speak with Mike I got mine from him for less than anyone else could do.And I needed him to put together a custom set to boot.

I'm not 100% sure on the cause of my broken rocker (I don't run a lot of spring pressure and a .590 solid lift cam), but I did find the valve cover gasket had sliped up and gotten "pinched" by the valve spring on that cylinder. Possibly coil bind??? Could have just been the rocker failed.

Todd is the man! Great guy to work with, and very knowlegable. He keeps stuff we need in stock.

Exactly, I don`t think the Cranes or Comps were designed for those pressures and that`s why I went to Harlands.............

Todd is great to work with. I would recommend calling him to set you up. I had some issues with my Crane rockers also and switched to Harland Sharps. Good luck.


Better get inside Ma. Looks like a storm's comin'.

T&D's are awesome, but cost a few pennies. Honestly I bought my Harland Sharp's from Performanceonly and have never looked back. I don't run anywhere near the lift you guys do, but still they work well for me.

I run a .630 lift solid flat tappet so I dont run the pressure you do but my brother does as he uses a solid roller like you. And we both run these Hughes 1.6 roller tip rockers. They have been flawless for us so far. I have only ran mine for a few months in my new 493 but he ran his all last year and this year so far with zero trouble. Ron

RAS makes a very strong rocker in stainless, good if you do a lot of street use. Very expensive, though.

You broke one, I'd expect more to follow , plus ditch those springs between them for solid spacers .
