7.3 gearboxes

Hey all,

I have a few Q's so bear wih me please!!

I am looking at different gearboxes to fit behind the 7.3 I am planning to put into my 76 F250 (big mod I know). Basically the more gears the better. A bloke has offered me a 6 speed ZF and 7 speed ZF gearbox, which he said might fit. Where could I get a belloushing to fit it made up and how many $$$$? Could I even modify a 5 speed bellhousing to fit a different gearbox?

Lastly the bloke selling the gearboxes wants to know the exact model of the stock Ford ZF 5 speed so he can look one up for me, thanks in advance, any help is good help,

Thanks nogo,

You wouldn't know if the bellhousing pattern on the back of the 7.3 is the same as anyother ford engine would you? Thanks,

7.3 gearboxes

I'm sure its different from all the gas motors . I found the model number its like 5s-ZF-42. I believe that 6peed should work I found this at a transmission parts site(http://www.drivetrain.com/zfford.html)

IDENTIFICATION - End loaded aluminum case with integral bellhousing. Tag is located on the left side of the case with a Ford code and ZF number 13-07-XXX-XXX.

# ZF Number OE Number Description
1307201060 F4TZ7005A Main Case 4.9/5.8
1307201062 F4TZ7005B Main Case 7.5
1307201063 F4TZ7005C Main Case 6.9/7.3

hope this help out

EXCELLENT!!! Thanks mate that was exactly the info I needed. I'll let you know how this 6 or 7 speed idea works as it goes allong. If anyone else has already done this or has any ideas I'd like to hear from you.

Thanks again
