GMC 250 Inline 6 Tuneup - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hello everyone. I am looking for help with tuning my 250 inline 6. I am looking for the steps to take but most importantly, the order I need to do them in. The carburetor and distributor have both been rebuilt. Spark plugs, wires, points, cap and rotor have also been replaced. Where do I start? Setting RPM? Points? Timing? I have a service manual so I know what the settings should be, but I'm looking for the order I should do these in. Thank you for your time!
