OK, looking for hard facts from the experienced FE builders, not "I think- I read- I heard" please. Are the "steel" gears supplied with the MSD #85941 distributors compatible with steel solid roller cams from Comp etc? MSD advertises them for use with hydraulic roller cams, no mention of solid rollers. This gear is also sold as #85813. I called the tech line this morning for clarification, and the response seemed very CYA, that they could not recommend the gear for use with aftermarket cams as they had no control over the type of material the cams were made from, contact the cam manufacturer blah blah, so a non-answer. He did state that the gears were "melonized steel". So, is this gear compatible with the steel solid rollers, and if not, what do the knowledgable builders use with the MSD distributors with the larger shaft and solid rollers? The Crane 34970-1 is (was?) for the stock Ford shaft size, and comes up as "not available" where I have looked
