If it was a standard shift flywheel the bolts are torqued to 55 - 60 ftlbs . . . that would be for a 7/16 X 20 thread diameter and pitch.

I looked in the Ultramatic section of the shop manual and came up empty.

Assuming the crank shaft is the same Ultramatic v Standard we can assume the crank is good to 60 ftlbs. Now the question is what grade bolts did you buy?

Another question would be how much of a lubricant is Loctite ?
