RV CAM TIming?

[Driven by Gears]

So i have a 1995 c1500 5.7L TBI with a mild rv cam what do you need to set the timing at with the cam i cannot find the cam card anywere do you still do factory zero? or do you need to advance the timing?

Start at zero, if you can't tune the PCM you can fool it a little by advancing the initial timing. Just watch out for Spark Knock (detonation). You can pull the spark plugs and look at them to confirm knock.
