I just tried elgincams.com - seems to be up at the moment. All I saw listed were Chevy SB hyd cams, no hydr roller retrofits listed and of those listed, nothing jumped out as a match.
I have heard that F-M makes cams for other labels but don't know who.
BTW What is F-M's 'history' w/ making cams? I saw where Crane sold the old Camshaft Machine Company (they had Wolverine/Blue Racer) to F-M a few years ago but kept the Wolverine/Blue Racer names(?). In effect are F-M Speed-Pro cams essentially what would have been the old Camshaft Machine Company Wolverine/Blue racer cams?
