1968 ( 318 ) main bearings - Input requested

do drill the thrust as I pointed out above with that stick shift
looks really nice
be sure and dial in the bellhousing
early blocks were smaller on the thrust machining but I do not know when they went larger
you can do the clearance along with a line bore
but oiling is maybe more important
with the clutch depressed all the oil wants to go out the front
sitting with the clutch depressed with a heavy clutch almost never works and is not good for your throwout bearing either
