Re: Are rocker arms typically non-linear in ratio?

Just a bit of trivia. In the mid-1960's, Harvey Crane checked every engine that he could find to see how linear the rocker arm ratios were. The most linear rocker was the MG TD I4. The least linear was the early Olds V8. Regards, Chase

Re: distributor gears and cam cores

I always make sure the block bushings are replaced / in really good shape. As Walter pointed out, limited option for what is technically the oil pump drive gear on Mopar: stock, bronze or steel from Crane Mike, which of the above should I use with one of your hydraulic roller cams? The Crane Meloni...

Re: Using grooved 396 cam in a later block?

it could cause a big internal oil leak at that bearing and I always soldered the original cam bearing hole shut and drilled a 1/16" dia hole for oil This is an urban legend perpetrated by a well known tech writer in an article for a very popular performance automotive magazine in 1967. The only way...

A Cam Dynamics grind would be 10R, not R10. Perhaps Reed, or early Lunati? Chase

Re: cast iron cam - surface treatments other than nitriding?

I was dabbling with coatings a while back. I had a seasoned chrysler customer that was experiencing early cam failures using a factory performance cam in different engines. I think rodders call it the purple stick due to some paint on it. It had no treatment at all from the factory. Anyway, we deci...

Re: couple of Morel roller lifter questions

Is anyone making rev kits for the small block Mopars? Nope. I had ideas for one years ago. There is no real easy way to do it with the 59* LBA block. I'm not sure how much it helps. I've seen my share of failures with and without them. The tough part is the angle between the pushrod and the lifter ...

Re: Older Crane Cam ?

The Crane Cams TR series of lobes were introduced in the late 1970's. Intended applications were for extended periods of racing where valve train stability was paramount, such as oval track, road racing, off-road, offshore racing, radical street, etc. Are there better grinds available nowadays? Cert...

Re: Lifter link bar

If they were Crane with circlips, they would be over 30 years old. The image from May 30 above could be Crane, but the one piece rivet still indicates 25+ years old. Regards, Chase

Re: Lifter link bar

Is it a circlip or a round wire ring that retains the axles? What this the O.D. of the roller wheel? Thanks, Chase

Re: Lifter link bar

If those are really Crane (locking bar doesn't look correct, and there's lots of knockoffs out there), they are well over 25 years old. The one-piece rivet holding the guidebar, plus the black oxide and minimal radius on the necked-down band on the body are the clues on that. Are the axles retained ...

Hi folks, yes, hung it up in January of 2016, after half a century at Crane (sounds longer that way).

Ford used the Crane/Cam Dynamics die cast aluminum rockers on the Cobra 5.0 engines from the factory without trouble. Ford used the Crane rockers on the F150 Lightning with the 351 Windsor AND Chevy used Crane rockers on the 1996 LT4 Corvette motor......BOTH motors had recalls for rocker arms....Al...

Re: Help identify this cam

This is a private label performance cam manufactured by Camshaft Machine Company in Muskegon, MI. They would have been sold to many vendors. They don't usually deal with the public, but perhaps give them a call, and they may help you out. Regards, Chase
