Locked timing , yes or no

joespanova · 04-28-2014, 12:26 PM

In a drag race application , big block , automatic ..........any point in a vac advance...............I would prefer it just locked out .

This post is to advise someone else..............I want a concensus so he can decide.

Vacuum advance on a race car? Absolutely not.

The distributor should be completely locked out, and timing adjustment should be done by the ignition box

Be sure that you have a start retard or you're bound to have serious kick-back issues during starting. Some start retards are built right into the ignition box and it may be just a matter of hooking it up and setting it.

Drag race application...check

Big block...check

automatic...check

and the timing on my 950HP 522 is NOT locked out!

Easier starting, no kickbacks, no chipped flex plates, no busted starter drives.

MSD billet distributor, with largest bushing installed. Full advance is all in at 2200 IIRC.

I can see that........I think he ( the guy this is about ) just needs to spend more time with the distributor.
