Please school me on big block truck vs car bell housings. My truck is an '82 D150 with a slant 6 and a '68 road runner A833 4 speed 23 spline(yes, it has an adapter ring). I'm looking into a 440 with a 10.5" flywheel and clutch. Can I use a 10.5" big block car bell housing with the slant 6 Z bar, or does it need to be modified?
