=====================================
Ummm....261, Leon, not 216. My Motor's Truck Repair manuals provide a
little more information.

The 261 first shows in 1954 with a compression ratio of 7.8, max hp
135 @ 3700 rpm and max torque 200 @ 2000 rpm. The last listing is in
1962, by which time the compression ratio had gone to 8.0, max hp to
150 @ 4000 and max torque to 235 @ 2000 rpm.

No engine weights are listed in my references. If you want more
information about the engine or about old GM trucks in general, go to

register for the Stovebolt Page forums and post your questions there..
They are

"for the discussion of topics directly related to the care,
restoration and use of antique GM trucks"

defined as pre-1973.
