What year corvette? I have specs for my 2006 Z06
On my Z06
Exhaust manifold torque is 11 ft lbs on first pass, tightening from the inside bolts and working outwards.
and 15 ft lbs on the final pass. I torqued mine at 25 ft lbs. I spoke to other mechanics and some of them don't use a torque wrench.
They tighten bolts in several passes in specified bolting sequence.
Spark plugs according to the manual are 11 ft lbs
Driveline tunnel plate is 89 inch lbs.
