1974 D300 360 fresh rebuild will not start
PRH, let's let him do another compression test now that he has it in time.
Guessing he did not have the throttle plates open on the carb to allow the proper amount of air to enter the cylinders.
Makes a big difference having the carb butterflies open. Have done this myself, poor compression reading across the board with the throttle plates closed.
Think this is his next step, to open the throttle plates and compression test again.
Could be ficticous low compression by doing his test wrong. Hope so, then he can fire it up with some thin 5w30 engine oil and zinc additive.
Now he can start "Breaking In" those new rings on those smooth non-honed cylinder walls. Needs to get it up to temp and run it good for 2 to 3 hours , to set the new rings to the cylinder bores.

As you were talking about them building the engine without glaze braking or light honing the cylinder walls.
That was a poor recommendation by his machinist, especially with the new rings going into those used bores.
