Camshaft for 273

The Commando cam works very well. We measured an original 67 Commando cam with 50,000 miles on it at Racer Brown's Cam Doctor's Analysis.

Intake:
110.4* center ATDC
202.8* duration at .050 Crank degrees
.405" net valve lift

Exhaust:
110.4* center BTDC
202* duration at .050 Crank degrees
.414" net valve lift

He can custom grind some nice smaller solid cams that have worked out nice. He has a 200* duration that works for either a 2 or 4 barrel carb and a 210* duration cam for a 4 barrel carb. The cost is not that high either.
