Mind the gap

[Luckydug23]

Hello Scramblers
Condenser and points in, now to set up (Challenger 36MX4 running on 95 -98 unleaded (non ethanol).. Any advice on gap and timing..As you may have guessed I don't have any service notes but would also appreciate hearing advice on personal experience. From previous posts I am guessing gap is around 15 -20 thou & timing around 3mm BTDC.
All assistance greatly appreciated
Regards Dug

Although I have not run a 360 myself, Greeves Service Notes GMC157 specify timing at 4mm maximum, 3.5mm minimum BTDC, with points at 0.016", Dug, so you're not far out! They also say fuel should preferably be 100/101 octane, and not below 98/99 unless the compression ratio is lowered.
Hope this helps?
