[Tigers] 347 stroker with overdrive

[Smit, Theo]

You can definitely damage an engine from over-advance (I've previously
blown a head gasket from an over-advance problem), but you're going to
be giving up a lot of drivability and mileage by not using a vacuum
advance distributor if your intent is to use the Tiger for highway
cruising as a significant part.

How long is their warranty period? You could run a mechanical
distributor for the first year or whatever and then switch over.
