Stroker specific cams (Part 2) cam reveal
Chevy cams is probably the wrong way to say it, It would more properly be called Chevy lobes. The cam itself would be designed to fit a mopar, bearing wise, spacing, etc. The lobes themselves are ground to work with "any" size lifter bore, rather than creating different lobe profiles to take advantage of Fords benefit over Chevys, and Mopars advantage over Fords. Economies of scale, especially considering Mopars are the smallest number of sales.
It has been explained WHY way better than I could do, (that & I type super slow). Google it, & it will probably lead you right back to whatever thread right here on FABO.
