yea not sure about part numbers, i race quarter mile around here so i wonder if i could turn od off too??? and also i noticed my truck ran faster time when i launched at 1600 rpm and shifted at 2800 as to shifting at 3000 and launching at like 1800 or so do u think it runs slower when i crank it to 3000 because i have a stock lift pump still and its not suppling enough fuel? and i wont shift past 3 untill i get better valvr springs

 

tuned the afc as u told me and what a difference it spools up quicker and doesnt get hot so quick, advanced timing more close to pump top hittin the head seat-o-pants-ometer says it feels faster ill let u know friday when i take it to the track,

 

Is that new mexico in the back ground.
