The FSM shows size and torque specs, but not the length.

Any chance you can share that info?  I don't have a FSM unfortunately.

Thanks so much.

Make sure the back side of the bolts you pit in the cam gear do NOT contact the block behind the cam in any way.  I don't think they are even 1/2: long, at least not on a 56 365 engine

I was going to say that I remember them being only about 1/2" long, but didn't want to give incorrect info knowingly.

Nathan, I don't have my Master Parts List here at the house, but I do remember that the cam sprocket bolts are a grade 5 bolt and had external star washers under the heads--not sure of the length, sorry.  My 1959 390 used studs for the oil pump mount, with split lock washers and nuts to retain the oil pump to the rear main bearing cap.

Look at the attached, if I have it right the cam sprocket bolt is 5/16-18 and 3/4" long. 

[Daryl Chesterman]

Nathan, you can see in Glen's posted parts picture that the oil pump is mounted to two studs on the rear main bearing housing.
