Motor options besides 1F

[RedFj76]

Hi everyone, Im new to this page so bear with me please.
I recently got a barn find BJ40 4 speed with no motor. Needing a motor I found a very cheap 1F motor with a 3 speed to put in it but will not be able to use the 4 speed gearbox as the input shafts are different . I really want to use the 4 speed gearbox. Im currently in the process of taking it to shop and having that 1F mounted and will have to use that 3 speed but before I do I would like to hear if anyone knows what other motor could be used and fit right into that 4speed input shaft?
Thanks,
Pete

On the gas engines (F/2F) the 3 and 4 speed bellhousings are different, but you can bolt a 4 speed bell housing to a 2F. (You can also adapt a GM 4 speed to a Toyota 3 speed bell housing.) I dont know about B series 4 speed input shafts but suspect it could be swapped. I plan to put a 4 speed behind my F engine and have been gathering parts. Call one of the good cruiser shops and they can set you right.

Why don't you put another B series back in? That's the easiest method...
