[Leon Rennebaum]

Had a TM1 on my 56 150, 327/365HP. Ran great once you got past 4500 RPM’s. The only thing that saved this combo for the street was the addition of a Skip Asay plenum divider. And had I taken the magazine article seriously about securing the bottom of the plenum divider plate so that it wouldn’t vibrate, the retaining ear of the plate wouldn’t have broken off and taken out a cylinder!
