Bought my first timing light, giving it a go. what degree?

[Mrturner1]

well after asking a million questions about all the things I'm doing to my C-10 front to back, it became obvious that I need to be fluent with my motor and tuning if I'm gonna get the most power and reliability out of whats already there, and without farming out the labor for everything. So I got a timing light from Oreilly's Auto Parts. It's the mid grade one with a dial on the back that goes from 0 to around 60 or 80, something like that.

My question is, what timing do these trucks typically like? Or is there even a standard? I have an MSD distributor, big lumpy cam (not sure of specs YET) Edelbrock Performer intake, and Edelbrock 650 carb. Long tube headers and 2 1/4 pipes to flowmasters that dump after the rear axle. Not even sure if those things are info you guys need but I figure if timing is unique to everyones ride, the info may be important.

I have no idea what the timing is now, so if somebody could tell me how to find out with my new timing light, id appreciate the insight. Also not worried about having to run premium gas, as thats what I put in every time anyway.

Thanks guys
Matt
