Jim,

Specs from my Bowman Torque Card for 140,000 PSI bolts: 7/16"-Dry threads=64NC/72NF

Oiled threads=38NC/43NF

1/2"-Dry=98NC/110NF

Oiled=59NC/66NF

185,000 PSI bolts: 7/16"-Dry=96NC/108NF

Oiled=58NC/65NF

1/2"-Dry=145NC/165NF

Oiled=87NC/100NF

Note: all numbers are feet pounds

For reference: 318 flexplate/crank=55

plate/converter=270(inch pounds)

Good morning Mopar Weekend Warriors,

May I have your thoughts on how much to torque down the following:

- flexplate to crank bolts. 8 bolt crank with big nasty 1/2" bolts

- flexplate to torque converter bolts. Bigger hemi-style 7/16" bolts

All bolts are ARP 12-pt if that means anything, as well

These are obviously nowhere near stop so my shop manual is not helping.

Thank you,

Jim
