Re: Torque values and such
Bill, your motor is a 351W, your flywheel/crank bolt holes (7/16 unf)should be blind & therefore dont require thread sealant. The torque for these is 75/85 ft lbs, the lower figure for Auto Flex plates which quite often use a shorter bolt ( less thread engagement ) and the upper 85 ft/lb for the proper flywheel bolts which should have a plain shank of about 1/4" for a dowel effect before the thread starts and have more thread engagement. These figures are for OE ford bolts, if using ARP or other aftermart hardware follow their torque values/reccomendations.
The 5/8"-11 bolt you refer to might be the central bolt for the crank damper/harmonic balancer, if so torque for it is 130 ft ib...
