Hey All,

I'm tearing into my 70' 350 and I'm wanting to check the crank journals diameters to see if machining is required. Does anybody have a list of what the crank journal diameters are or what their tolerances are. I have a service manual that shows me all the specs i need but its for 77 and up 350. I know the blocks and items changed from the 76 and prior blocks and I don't want to use those specs if they are wrong for the earlier engines.

Any direction? Thanks in advance

Matt, as other will say, buy the proper year factory manuals, it will make tearing into it so much less complected.

I'm fairly sure all SBO have the same crank specs, no matter what year they are.
