flex wheel torque?

[shaun89]

i dont no if im just stupid or something but i cant find what the torque specs r for a flex wheel in my haynes manual. i did a quick search on google and found 60ft lbs on some hot rod forum, im just checking if this is right. o ya, its a sbc 350 if that matters.

85-earlier 60 ft lbs
86 and later 75 ft lbs
big block 65 ft lbs

Chapter 2 section A pg 2 of the Haynes manual.

For reference, it's called a flexplate. Depending on what year you're working with the later ones with a one piece rear main seal are CRITICAL about the torque. If you overtorque the flexplate on late model engines you can ruin the sealing surface for the rear main seal and end up with a leak that will NEVER go away even after changing the seal. The bolt circle is fairly close to the outer edge of the crank and overtorquing the bolts can crack the crank from the bolt holes to the outer edge.
