REFINISHING: A process by which the cam face is refinished to the same geometrical shape, however, being slightly smaller in size.
REGRINDING: Refers to an operation where a stock camshaft is modified to racing specifications. This should only be done where it is difficult to obtain new cores, as with imported cars.
This is from the ISKY catalog. My understanding is that if a present cam is regound (resurfaced) for a stock rebuild, the cam lobes are reduced in diameter, requiring the use of longer pushrods to allow for the change in geometry.
Also, there are different billet materials used for different cams, say a stock hydraulic as compared to a solid roller.
I have exchanged information with another MEL freak (well, absorbed his information mostly) that has had a custom cam ground. I promised not to mention the name of the grinder as he feels they don't really want the aggravation of custom grinds on this engine series. But, it is possible (though expensive).
Once I decide which way to go (430 compared to 462 and strokers), I will go to the source and ask for a special cam. The timing events that were hot in 1958 surely don't measure up to today's standards.
I Am Presently Looking For Any Factory/Aftermarket Parts/Information Regarding The MEL Engine Series
Also Older FORD Special Service Tools
