350HO crate. Service manual 12487544.
See the picture from the manual below. It says: ....The HEI vacuum advance canister should remain disconnected. This engine is designed to operate using only the internal centrifugal advance to achieve the correct timing curve.
(Yea, I actually read the manuals.)
So, set at 10* at idle and that's it, no vac advance on this one? Except for a bunch of antiques, I've never had an engine that didn't use a vac advance.
