Header dilemmas- 67 Barracuda FB w/383

Flywheel:

10.5" 130-tooth ring gear: YES, headers will clear.

11" flywheel, 143-tooth ring gear / 383-400 B-engines: NO, headers will not clear.

11" flywheel, 143-tooth ring gear / 440-RB engines: YES, headers will clear, however, you must use a RobbMc Performance starter #3005.


Clutch Linkage:

OEM ... A-body applications with a Standard transmission requires a modified Z-bar. Modified Z-bar sold separately #ZB307.

Interesting the "shorts" won't clear a RB with 143 t - 11" flywheel without a 300+ starter. They have the same FN for the "long" tube.

I cant imagine why one would need the mod Z-bar with "shorts" though.

Even the Schumacher's need a mod for the stock Z. Several here have posted their fix.


......I included the side shot so you can see what I mean, along with a photo of driver’s side header.
I did these on my 440 years ago to replace same from the late '70s. I can't tell with the picture you provide whether they are the same or not. Allegedly fit a B engine as well.
