I am getting some conflicting info. I have a 1967 Firebird that originally had the 6 cylinder in it. It did get a 400 at some point, but they welded the motor mounts to the subframe. They just tacked the corners, so an easy fix.
The question is.....did the 6 cylinder subframes have the V-8 motor mount holes? I have heard yes and no. Does anyone have a picture that can show the Pontiac holes and the Chevy holes?
Any help is great. Thanks.
