Yep, My point was, I was wondering which cam was in those flat-top blocks:
Std. 273 2 Brl (8.8:1):
Valve Lift: 0.395" 0.395"
Duration: 240ø 240ø
Opens: 14ø BTDC 58ø BBDC
Closes: 46ø ABDC 2ø ATDC
273 Commando (10.5:1):
Valve Lift: 0.425" 0.425"
Duration: 248ø 248ø
Opens: 14ø BTDC 56ø BBDC
Closes: 54ø ABDC 12ø ATDC
Without at least checking lift it's tough to know what was actually in those cars.
