Gentlemen, I need all tightening torques specs for my '25:

1. Crankshaft Bearing
2. Con Rod Bearing
3. Engine Flywheel
4. Cylinder Head

Thank you once more!

I torque the cylinder head to 50 foot lbs. On the rear axle shaft I torque the nuts to 125 foot lbs. I don't use a torque wrench on any other bolts. On crankshaft bearing and flywheel I use a 1/2" drive breaker bar, on the connecting rods I use a 3/8 breaker bar. On the original connecting rod bolts the threads are easily stretched so you don't want to over tighten them. You might want to use Chevrolet 350 connecting rod bolts and nuts for your final assembly instead of reusing original bolts.

Folks usually use 45-50 ft-lbs for the cylinder head. Ford didn't use torque values, since torque wrenches hadn't been invented yet. (I'll stand by while others refute that last part with evidence to the contrary.) :-)
