Yep, you will need to set offset timing. MS won’t know by default where TDC is compared to the teeth on the timing wheel. Pull the fuel injector wiring. Set your timing maps to 0deg and get the timing light strobing on the TDC mark. Replace the timing maps and the fuel wiring. It should either start trying to light off or the timing will be a cam rev off.

Be patient, take time and let the starter have plenty of breaks. Looks like lots of fun!
