Hi Jon,
The Norbar should be fine for the Austin engine small stuff.
Yours will be too light for the flywheel nut.
Big ends about 18 ft Lb
Head Nuts about 18 ft Lb
Block can not be done with a torque wrench so you have to make sure all the nuts are evenly tight.
assuming good threads in the crankcase I suspect 11 ft Lb.
Maryland metrics have a very good Torque Chart.
The idea is to slightly stretch the bolt / stud but stay within its elastic limit.
Sorry for my earlier error as I use 35 ft Lbs for my big ends on an 1 1/2 crank ( 3/8 UNF Bolts )
Top Quality 5/16 Bsf X grade will take 32 ft Lbs
