I have a question for the 400 engine experts here. I have a 170 in my 71 Bronco, and I want more power. I have a 400 motor sitting in my garage that needs rebuilt. I need to know what my options would be for a manual transmission if I decided to put the 400 in my bronco. First question is how can I tell if I have the block with the big block bell housing pattern or the smallblock? Also, if I do have the big block pattern, what are my tranny options? I was thinking of using a ZF 5speed when my plan was to get a 351, but I don't think the ZF will work if my block is the big block bell pattern. Does the back of the big block BH have the same bolt pattern as a small block bell would have? If so, then I should be able to use any manual that would bolt to a small block including the NV4500 and 3550(with proper adaptors of course). Any help would be greatly appreciated.
Thanks!
Thanks!
