optimal timing * and fuel pressure for my setup?

[IndyBlk5.0]

title says it all, take in concideration my mods, cam is put in straight up, no advance or retardation... need opinions with my combo... thanks guys

ttt anyone throw out some numbers?

it's impossible to tell you what optimum is without a wideband dyno-tune. if you're looking for guesses...

14* advance
38-40psi

Hes dead on with dyno tune...just put down the money and have it done right. Skip the headache you will get with the guessing game.

There's nothing particularly exotic about your set up - the other guys are right; set it at the 'usual' - 38-40 on pressure, try 14 or 16 on timing, back it off if it pings. Even if you dyno, remember that the 'learning' features of the computer are going to undo any changes you make to fuel pressure over time with pulsewidth changes if such changes take the car far enough from the a/f ratios the computer's trying to control to. If you really want to tune it - you need a chip/tuner/tweecer to alter the advance curve and fuel scalars at w.o.t.
