Been doing this for 45 years. Set your static timing to 10BTDC, fire it up and tune the carb for the best idle you can get then, with the engine running, start pulling the timing advanced until you notice it stumble a bit, go back a touch before that point and lock it down. Should run good then. Let us know.hoping someone on here can offer advice or a solution to to my quandary. - Rubuilt my 360 sb some time ago…..030 over; speed pro hypereutectic pistons ; Clvite bearings; Hastings rings; 11.2 :1 static compression mild cam and re graphed ignition initial 16BTDC. Recently ran the camshaft in using an engine test stand . Ran it for 20 mins varying revs etc as per proper run in procedure. Engine is now in the car and starts up perfectly runs solid, crisp sound response on throttle is brilliant and oil pressure sits on 60PSI. Problem is, if I run it and bring up to temperature and then try and restart it, the battery struggles to turn it over. Battery showing 12.2 volts so I’m sure it’s ok. Engine was very tight whe turning by hand before initial run in of the cam. Any thoughts??! TIA
Not a ground issue if it starts ok cold. It is a heat issue.....
Funny, this is what you said as well. 12.2 is low but should crank it.
Have at it.
I have seen 12.2 volts make an MSD box not happy to the point the car wouldn’t start
Crank, maybe not fire. If it struggles to crank, likely has something happening with ignition in the chamber.I have seen 12.2 volts make an MSD box not happy to the point the car wouldn’t start

Funny that the guy saying this stuff also says that MSD aren't sensitive to voltage. I'm out.
Simple diagnosis stuff, pull coil wire, try it, add a jumper try it. Hillbilly stuff to narrow the issue without any conclusions.
