The new Su8 easily outperformed the V-12 and the unit sales couldn't possibly justify keeping an antique motor. The unit already was weakened by the bore and stroke method of increasing horsepower. Cooling system wise it was a thermal efficiency disaster. So any multi-cylinder project would be a waste of money without a blank sheet of paper.

GM did that when they authorized the OHV V-8. They dropped the V-16 because the Hydramatic made those cylinders unnecessary.
