SB bell housing -734

The overdrive bearing retainer can't be machined that far. It would leave only .097" to the outside of each bolt hole. Aside from being weak, the heads would overhang anyhow. I've seen people hog out the bellhousing hole, but that leaves very little material between the opening and the bolt holes for the fork pivot. Neither is recommended.

The application is 1972-'76 small-block, all body styles, except overdrive transmission. It can be used on all 1967-'71 models with a 10.5" clutch if the 1968-'71 ballstud/bracket is used (the BSB734 is a reproduction).
