Re: Crankcase Bolts



Please be aware, those bolts (without the groove) can only be used in the late style, big oil hole crankcases.

If used in an early style crankcase, immediate engine failure/destruction, is pretty well assured.

In an earlier thread there was mention that the best choice for crankcase bolts is "late model bolts without the oil groove...". I have 5 blocks but none are late model. Service Motors doesn't offer these bolts. Any idea where I can get them or is there a substitude?
