MSD Streetfire Dizzy

[jdheff1982]

Curious if anyone has any experience with these. I plan on getting it plus the streetfire plug wires. It does have an adjustable vacuum advance, however, the table MSD provides is confusing to me.

My vacuum is sitting at 8.5 hg at manifold. So, would I leave the canister @ 0 turns to get the 14* initial advance?

Is installation really as easy as pulling out the old and putting in the new with reference marks to retain timing? Last thing, will the hood need to come off to make removal and install easier?

Thanks.
