Re: PROJECT: How would a Chevrolet dealer build a shop truck in the early 1970s?

Progress. Had a little time over Christmas break.

Starting to put it all back together.
Over the last several months the '72 front crossmember was cleaned and painted and installed in the '70 truck.

Torqued the cross member mounting bolts in this morning. One spec I found said the ones that go down into the frame are 90 ft-lbs and the ones that go out into the sides of the frame are 65 ft-lbs. Strange to have the identical 7/16" x 1.5" Grade 8 bolts that bolt together such similar material having such different torque specs.

Also, before the holiday break, the block was cleaned, deglazed, and painted (used the 1955 "orange-red" instead of the later 1970 appropriate "orange" because I liked how the darker color looked). Thread chasing and more cleaning today.

Also a shot of the hypereutectic pistons mounted on the resized rods and the forged crank kit from Rock Auto.
