My 2 cents, the DB4's I have seen do not have the threaded boss for AC compressor brackets, is you have factory AC car.
Offenhauser did have those mounting points, but they incorrectly located the throttle cable mounting point to match the 2bbl Chrysler manifold, instead of the 4bbl location.
If you have and desire to use Chrysler kickdown linkage, that also needs some changes for 4bbl.
Good info, thanks! Don’t have A/C, so no compressor mounting points needed. Will needed the kickdown linkage, what changes need to be made? Do I need a whole new assembly or can I make the 2BBL one work?
