SC304 OP enthusiast S Joined: Nov 2004 Posts: 287 Michigan	Looking for information on adjustable rocker arms that will fit gen 3 heads with out machine work. I currently run Jesel rockers in Super Stock but I'm building a Factory stock motor which is an all aluminum 426. Cannot modify the castings. The stock rockers don't have any adjustment obviously. I have heard of Harland Sharp and T&D rockers. Anyone have any experience with these or anything else? Thanks for any input. Mike

I have heard HS has had problems with castings. Rocker ARM specialist should be out end of April. No confirmation just rumor. What about adjustable pushrods?

Lemme ask this....what rocker systems are the 9 sec LX cars like Red Baron running....and the 8 sec Drag Pak cars like Dave Barton......and are they breaking them? 67 RO23 clone with 6.1 SRT Hemi and dual quads. Soon to have Drag Pak induction and Throttle body.

MattW master M Joined: Jun 2005 Posts: 2,776 Ontario Canada	So here's a couple of questions. The reason for adjustable rockers is for a solid roller, right? Is it possible to use the factory rockers with a solid and set your lash with custom pushrods? Isn't the whole idea with super stock or any HP engine is lightweight parts? Rev quicker? I don't think any of the aftermarket would compare with the weight of stock rockers. Matt

I threw the post up here to try and find feedback on any rocker arm info available. The RPM's are expected to exceed 8500. For a clarification. My post started with a reference to Factory Stock. It's actually the new factory shoot out class. Mopar 426 in a Challenger, against the Copo 427 and the Ford 429 in a Cobra Jet. As I stated earlier I run Jesel on my 6.1 and 6.4 heads in super stock. Jesel does not have an offering for a Stock replacement rocker. Totally different rule book though in factory shoot out with the 426 in Stock. Cylinder head and intake is Cnc'd, valves are Ti, compression is 15:1 all in the Aluminum block with a solid roller and lifter under a large throttle body. Controlling lash is the most Difficult. We have made dyno pulls and witnessed Geometry Fluctuation lets call it. Lol. 8007973-image.jpg (2963 downloads)

He told me he does not know how you could get a socket or wrench on adjuster nut..... You certainly can use lash caps or adjustable push rods with stock rockers but would take hours to set valve lash.

Don't think that push rods are the answer but certainly an option? The acceleration is great but it has to be stable thru the acceleration and at max RPM you hope right? So lighter is always not the best scenario. Harland's are Aluminum while T&D is steel. Speaking with Harland's Engineer I don't think they intended the rocker for the application described in this post? Not knocking the product as they had a different target market? Just like Jesel had no plan to sell their rockers as a stock replacement.
