My Barracuda is a 73, however a 70 340 has been dropped into it. What is the correct amount of oil to put into an early 70 340 motor? Simple question I know, but I've not found the oil capacity chart for this motor. The oil pan is stock. As far as any changes to the motor, it has a .030 over rebuild and I have had to go to the 90 degree oil filter adapter with a short filter because of the exhaust.
