Bell housings

I think I've found an FMX with a big block bell attached to it at one of the local junk yards. Now providing I'm right, will I have any trouble bolting it on to a C4? I want to swap the 302 in my 72 Gran Torino out for a 400 without too much in the headache department so any and all advice would be very helpful.

Thanks in advance!

Sorry mate won't work.. The FMX bell is way different to C4....

You need to look for a C4 in a 77-78 T-bird or other big car with a 351M.

I'll make sure to double check it against the other trannies that they have there.

FMX bell is attached to the transmission with 4 bolts.

C4s use 7 if attached using the pump bolts or 5 bolts otherwise.

There is only one big block bell that fits a C4, and it will ONLY bolt to a C4 with the dipstick in the pan. It will not bolt to a C4 having a dipstick in the case.

Unless you go to an aftermarket BB to C4 bell they fit on the pump bolts on any C4 case.
