Allright, I'm looking to put a 390 in front of an NP 435 that was attached to a 300-6. I have the 390 bellhousing and clutch assembly, so I have everything to hook it all together.

Question is this:
I hear that there is a difference in the length of the input shaft between tranny's that came behind FE's and the trannys that came behind everything else. Is there a significant difference or does the bellhousing make up the difference?

My understanding is that the difference is in the bellhousing, that is why the truck housing , if I recall correctly, is a little deeper than the car bell housings (car trans vs truck trans). I do not believe the trannys had different length shafts, that would considerably limit their applications...

I got the tranny question sorted out over in the transmission forum, but I'll keep the bellhousing idea in teh back of my mind. I have a bunch of ford bellhousings hanging around, compare them to see if there are any depth differences.
