I'd like to know too!! Is there a give rule of thumb for timming retard per lb of boost? Cause i plan on running 16psi after in a few months wheni get the engine rebuilt.

Patrick (used to post here.. haven't seen him in a long time) ran 18PSI with no timing retard for a good while on 440's, a 4:1 disk and SAFC. Ran a best of 13.8 on street tires.

>(Can't afford to dyno tune....)

Which can you afford more than the other. . .

.... Dyno tuning or complete engine rebuild?

Nicely put Evul, even on the Dyno I have learned you could blow a fully built motor. :( Of course that was at 22 psi shity rebuild and no timing retard. WoW I think about it now and I am not suprized she blew up.
