1969 Mustang bellhousing for big block

Post  JBR-3 on May 14th 2017, 10:25 pm

Is the original Boss-9 bellhousing the only one that will have sufficient clearance
in the tunnel, that is, without using a BFH on the firewall ?

I have the Lakewood bell, and I have an aluminum truck bell ( casting # E7TA-7505 ).

One of my projects is to put a Boss motor in the '69, with headers, and I am
seriously considering going with a C6 if I get too pissed off with the Z-bar - vs - header issue.

Car is not an original Boss, maybe I should cut out and redo the firewall.

With a fat headed boss the trans will be the least of your problems. A c6 will fit with no problem,l have no experience with a standard trans.

Hack that SOB for all the clearance you need!!...sheetmetal is easy to reform, reshape, and re-weld!!
