Don't understand guys running 12 to 17 degrees initial. Would like to see the rest of the curve.
I run 17 degrees initial with the mechanical advance adding another 16 degrees for a total timing of 33 degrees. I have a 10 to 1 440 based 493 with the MP 528 solid cam.Don't understand guys running 12 to 17 degrees initial. Would like to see the rest of the curve.
Maybe a dumb question, but here goes.
Using a dial back timing light, why can't you set the timing to 34 or 35 degrees, run the RPM up to 3000 RPM and adjust the distributor til your timing shows zero on the timing mark and lock it in there? I did it that way and my initial timing was at 14 degrees. That's where I left it. Seems to be running fine.
Would that still be true with a MP orange box ECU and distributor?
