The Crane aluminum roller rockers have been good for me for the last 12 years.
72 Cuda, owned 25 years. 496, with ported Stage VI heads, .625 in solid roller, 254/258 at .050, 3500 stall, 3.91 rear. 850 Holley DP, Reverse manual valve body.

1999 Trans Am, LS1, heads, cam, headers, stall, etc! Love to surprise the rice rockets with this one. They seem so confident, then it's "what the heck just happened?"

Harland Sharp seems to be on every race track, and they are aluminum?

 :clueless:  I believe he mentioned for street use. I would only consider aluminum if they are bushed. The
aluminum wears and then you pay big bucks to save them (if they can be saved).  With a bushing, you press out
the old bush and install new. Resize to shaft.
If I cant fix it, it's broke

ok, but I've got aluminum Crane Gold rollers that are seeing solid roller cam  .625 lift and 470psi open pressure springs, and for
12 years they seem to be performing flawlessly. I rarely have to adjust valve lash any more.

Also, and obviously I'm biased, lash adjustment is necessary due to metal wear. Since synthetic oil flows quicker at startup, and lubricates better, I think
thats another reason why my lash has rarely needed adjustment. For last 7 years, I might have to make a minor adjustment to one or two at the most.
And I may have just been being too picky when I adjusted them in the first place.

Yes they are aluminum and bad a$$....

The only shaft rocker of this style to feature heavy duty needle bearing fulcrums matched with specially heat treated, heavy wall, rocker shafts. Harland Sharp Mopar kits are designed for extreme applications with valve springs up to 1.650 diameter and .900 lift cams. The 7/16-20 x 5/16 ball adjusters are designed for use with the factory style pushrods, length to be determined after you have rockers installed. Kits include rocker arms, shafts, spacers, hold down clamps, adjusters and nuts. See our instruction link for replacement and service parts #s.

Well, street use can mean a lot of things. It can mean "grocery getter", or, defend the
Mopar honor against the new Camaros and Mustangs at all costs!.
