I'm re-assembling a GT6 engine, and am about to bolt on the flywheel using ARP
hardware. I'm puzzled at what seem to be low torque settings in the factory
manual of 42-46 lb, versus 58-60 for the bearing cap studs and 65-70 for the
head studs, all of which are the same 7/16" x 20 thread size. Is this a
function of bolts versus studs? If so, why haven't we gone to short studs for
this highly vibration prone location? I would think the main bearing cap
torque, where there is no gasket to compress, would be similar.
Lastly, should I use thread locker or grease? My inclination is to use thread
locker on these bolts which do not have any washers.
