I just got back from testing my truck on a chassis dyno. This will be my base line numbers. I am planning on installing the Holley carburetor and electronic distributor then do another engine test.
Max Torque: 140 @ 2000-2400 rpm
Max HP: 94 @ 3950-4000 rpm
The torque curve is very flat. Above 130 lbs ft of torque from 1400-3750 rpm. For an old truck that had no major work done on the engine it's impressive. No idea how many actual mileage it has, however I do know it been to Alaska twice from AZ in the early 70s. Once with a camper and once without the camper.
