Re: 58 Edsel engine
It was mentioned earlier in this post to use a 391 crank for a bullet proof engine. In the 70's and 80's I operated a machine shop and rebuilt plenty of FE and FT engines. The factory 391 steel crank is not the hot set up, they crack and break in the 4/8 throw. I recall at least 6 of them coming into the shop broken and several that were cracked and would have broke. Today I would buy a Scat product. FWIW, I've never seen a broken cast 390 crank
