I took this from a scientific publications workshop manual (32 to 48). I know some flat head v8s have nuts and studs on the main bearing caps while others used bolts. I cant remember if the figures are the same, so you need to investigate further. This book is good in that as a post war publication it covers well, (for examples) the carb and clutch rebuilds along with interchange of parts. etc not found in Ford publications.
I have bought parts from James Saccoccio of Gotham Auto parts in New York (00 1 718 878 3699) and have had great results from him (and also from Van Pelts)
