Hey guys, I'm assembling the bottom end of my 250 currently and need some advice. I picked up a set of Mr. Gasket crankshaft/flexplate bolts for a small block Ford and they have a set of those funky lock washers with the angled tips around the circumference of the washer. Alone, the bolts are about two to three threads shorter than the ones that came out of the crank. Should I use these on the bolts or just apply a little loctite to them? Anyone have any tips on keeping the crank still while torquing these down? It's up on a stand. Thanks

The rule of thumb is to engage a bolt at least the same as its diameter. So a 3/8" bolt has to go at least 3/8" into the threaded hole to be effective. Locktite will help prevent it from backing out, but won't make it any stronger if its too short.

In the case of a bolt into a nut, the bolt has to at least pass thru the nut.

Loose the washers and use the loctite.
