Hi there, I've got a bit of a project going here and I was wondering how much the flathead 4, 6 and 8s share, as far as architecture and what not. We have what I believe to be a 323 cu in flathead 8 spitfire industrial motor and my boss wants to use it in one of his hot rods. Not sure which body it is going in yet. Anyway, can anyone provide insight into just how much these engines shared with each other? Bore spacing is the important info here, but all info is welcome! bad ideas abound. thanks!
