Old crane cam help
Only number I can read is 69 16 89 HMV ???NC S/B HYD I think
Like Mr. A-Body-Bomber stated,
Crane HMV = Hydraulic Max-Velocity
The most popular Grinds were
* HMV-262
* HMV-272
* HMV-278
A 'dual-pattern' profile that emphasizes; good Low-End and very good
Mid-Range torque.
And a Camshaft that could provide a real-low Idle. Great for a 'Daily Driver'
with the best Power-Range at 2600 - 3000 RPM's.
Range ....... 1800 - 5400 RPM's
Max .......... 6000 RPM's
One of my old sheets on the HMV-272
Lift ...................... .454" Intake / .480" Exhaust
Duration ............... 272* Intake / 284* Exhaust
Duration @ .050" ... 216" Intake / 228* Exhaust
Center-Line ........... 112*
Overlap ................ 54*
Intake {Opens} BTDC ...... 25*
Intake {Closes} ABDC ...... 67*
Exhaust {Opens} BBDC .... 75*
Exhaust {Closes} ATDC .... 29*
Very nice with;
* 3.55 Gears
* Good Exhaust System
* A 'bit' of Compression
