Anyhoo, here are some things to consider: You ALWAYs want the rear main a little looser (more clearance) than 1, 2 and 3 because it has a larger surface area. Like wise, you torque the bolts down less because they're smaller and there's 4 of them. Your 0.0020" should be just fine.

In the real world, your rod bearings are more critical (bolt torque and oil clearance) - they're always the ones to let loose when anything lets loose.

Finally, 2Fs DO NOT use shims, F motors do. When you add a shim, you increase the clearance. We had to add shims when we were assembling the F for my 71 because it was way too tight without any shims and you couldn't even turn the crank.

so the rod torque spec is 35 to 55 ft lbs according to the 2f manual... why so large a range?
I picked 45 right in the middle ...
anything wrong with that?
