Good Day all; I have a question about the ignition timing on my 1981 380SL. Would some one please tell me what is the maximun ignition advance this engine can safely tolerate? Stock setting is 5 degrees BTC, but I would like to go as much as 10 degrees BTC. I run nothing but premium 92 octane and perhaps some Jectron once in a while. I also have a MSD ignition installed with intake and exhaust upgrades. Thanks for all your replys. -JK380SL (formally Jim380)
