I have a 1934 pick up that is a factory 4 cylinder and I have considered doing a later 8ba engine swap (engine just completed by Dennis Frings) and would like to know the over all difference in engine lengths? I have a rebuilt 39 trans that can be used with either of the engines ( I have the 1939 style Clings adapter for the 4 cyl ) other rear ends too. I can also look into one of the Corn Huskers T-5 adapter kits by Krylon if that would help in a conversion. Since these were offered in both 4 cylinder and V-8 versions, what might I need to look for or modify on the frame & mounts if I decide to go that route in the near future. Thanks for any help on this one.
