Default Crankshaft Pulley Bolt Size?????
Does anyone know what size bolts are used to secure the crank pulley in the 351 W harmonic balancer? I have tried several sae sized bolts but I am sure the balancer is drilled and taped for metric sized hardware?

Brent,

I have tried a 5/16 fine thread as well as several other fine threads. I am convience it is a metric thread but there are too many choices of thread pitch:

1.00 1.25 1.50 1.75 etc
