Vacuum vs. Mechanical Adv

I'm looking at a new ignition system and was wondering if I should go with mechanical or vacuum advance. This is in a ZZ Fastburn 385. Vacuum seems like the standard, but is there any benifit of going with the mechanical?

Anyone have pro/cons on the 2 kits in Summit with Kit 1 thier own brand kit and Kit 2 being the Mallory 6al Kit?

Re: Vacuum vs. Mechanical Adv

Vacuum advance is a supplement to mechanical advance and just adds additional tuna-bility which is a big benefit on the street. There are dist's that are electronic with no mechanical or vacuum that are very adjustible. A truly all mechanical advance works great for the strip and a lot of guys run them on the street or disconnect the vacuum from their dist but it's really a trade off.
