Wanna know what would be the proper timing curve for a LQ9 6.0L Ls1 engine carburated using MSD ingnition 6010, rod, pistons, crank stock, manifold dual intake, perf headers, compression ratio:11:1, heads casting 243,
cam: 236/242 duration, LS:113. I'm 1500 meters up to the sea level, and also the proper carb for this??? It's on a chevy colorado

Of course this is not exact but a ball park, all engines are different. try either 8-12 and or up to 12-16 degrees at idle, usually you would want all of your timing in (Say 36*) in by 2800-3000 RPM's..

You'll get a lot more answers if you post this in the carburated section.
