Re: Camshaft lobe designers

I'll add in Mark Stessens of Cat Cams in Belgium. Lots of made-to-order/application lobes. Good quality.

Just wondering who designed the 4541 and 4381 profiles ?

Re: Deep scratch- GM 454/438hp roller cam

This also occurs when the guidebar on that pair if lifters does not have the arrow pointing up, causing the wheels not to track squarely on the lobe.

It's a Cam Dynamics camshaft, ground on an 8620 steel core, standard journals and firing order. Call Crane for specs. Chase

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

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...

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...
