Hi, Hope your redo goes smoothly.
From the pic that you posted, you have a block from a 1450. Thats why you have the dipstick block-off plate. Another clue is all the holes that are drilled and tapped for the electric PTO. The black color of the block could have meant a "service block/engine" or the color that most quietline engines were painted.:biggrin2.gif:
