Default Flexplate Torque Specs?

Anyone know the torque foot lbs for the crank bolts on the flexplate?

I'm at work and don't have my helms book. I don't remember them off the top of my head, my friend is putting a new TCI flexplate in his car and asked me.

Thx.
Lee

i am thinking it is in the range of 25-30 first time around...then you finish off with like a 70-75 i think. Not compltely positive though......

i am sure someone else can pinpoint closer............. i think www.ls1howto.com has a torque listing on their site also.

Thanks for makin the post Lee, I appreciate it dude!!!

For anyone else lookin for the specs, I got 'em off a buddy out of the helms manual (or one of those type manuals):

Torque Specs for Flexplate -

First time through torque to 15 ft/lbs
Go through again and torque to 37 ft/lbs
Go through for the last time and torque to 74 ft/lbs
