im doing an 5.3 in my 91 silverado..and i bought the edelbrock carb kit,which timing pill would i need to use on it..going to do 224/230 cam b4 the no2...i read the chart it saids 1-3 for 5.3 n lower with high or low gears n 4-5 is for 6.0 n higher n 6 is for modified...im also be running an th350 which im getting tomorrow i hope..

but the plans for the 5.3 as of now is 224/230 cam
150-200 shot nitrous
750 chokless race carb
3500 stall
4-links(need ideas)
4.10-4.56's
fuelcell
weight reduction
4/7 drop
what ever when the time comes...anything might need lettme know

 

With th350, i would not go lower than a 4.10, we ran mine this weekend and i think i'm gonna swap to a 3.73 to make it hunt harder.

 

what is she runiing?
