Well, it seem the meet/show in Pensacola this weekend served no better purpose than to further my own confusion. I almost picked up a bell housing, flywheel, clutch assembly and all bolts for my 1969 Mach 1/351 W. The guy told me though that the one I was looking at was for the 302 since it was alluminum. He said the one I need is cast. Another guy said I could paint an alluminum housing cast color and no one would no the difference. so here is my question (Finally), is there a strength issue I need to be concerned with that would cause me to go with cast, or is there the issue of losing points on a concourse car if I had alluminum when it should be cast. If it doesn't matter either way, what would you do?
