Graeme from OZ, we are only supposed to consider Corvettes C4 and older on this site, but since you have such an interesting name, and I have the information at hand, I'm going to give you a freebie...

Maybe this is not the easy answer you expected...if I were building an LS7, I would have to buy the complete Service Manual for myself. From the 2006 Covette Service Manual, Engine Mechanical - 7.0L, page 6-539:

10. Install the bearing cap (103), bearing (104), and bolts (102).

Tighten

10.1 Tighten the bolts a first pass to 20 N-m (15 lb-ft).

10.2 Tighten the bolts a final pass to 75 degrees using the J45059 (GM special tool).

Re: zo6 ls7 rod bolts

Nice to hear from ya', Graeme. I hope my info was helpful...torque "by degrees" is not a familiar concept to me. Congrats on owning a Z06 "Downunder".

Re: zo6 ls7 rod bolts

It sounds like one of those designs that stretches the bolt beyond the elastic limit.

Re: zo6 ls7 rod bolts

Duke, is it possible the tensioning procedure as simple as 75 degrees rotation after the first stage torqueing to 15 ft-lbs? I'm wondering if you can just use a machinist's protractor if you don't want to buy the special tool.
