timming question?

[1LO94]

ok i have a 95 5.0 auto car.....so far it has gears, built aode, 3600 stall, long tubes....and full exhaust, c&l cai and mass air meter, trick flow stage 1 cam, and gt40 intake....since i did the intake i have changed my timming a few times...the place i got the cam from said to set the timming at 14 advance...well i take the car to the track last night and even on the street sometimes it starts to ping out like a spark knock...or timming off...or not enough octane...it was running 93 octane....well so i backed the timming down to base timming and it didnt seem to ping out any more but the time i ran did not improve any....so what do ya'll sugest setting the timming at...and what should a car with these mods be running close to in the 1/8th mile

thanks

hey welcome to the site didnt know you were on here. I from abilene also i drive the silver auto 5.0 in town. As for timing all motors are a lil diffrent. Im running 16 on mine with no ping and 93 oct in but from what i understand 14 is about the norm for them

what brand of 93 were you using? try changing brands. in my 99 suburban with 87 one brand would ping and another brand wouldn't. maybe it's thats simple
