Timing help!!

With the modifications already made, forget standard timing peocedures. Warm the engine to normal operating temperature; advane throttle to 2600 RPM (3000+ withMSD); set total timing to 36* lock dist. Return idle to street RPM and read degrees on timing light. start and stop engine to determine easy starting and shutoff without dieseling. This pwocedure will get you close and slight adjustments could be needed.
My personal preferance for mopar small blocks are MSD wires and Autolite 66 plugs. Good luck with any tuning method you use.
