I'm having problems finding local sources for 403s as its a bit of an oddball engine since it was only offered for a few years and I was wondering if it might be easier to hunt down a different Olds small block

Any SBO will have the same bolts as a 403 EXCEPT the head bolts. You'll need head bolts from a 77-up motor, since Olds changed from 7/16" to 1/2" on the later motors.
