Crazy idea

But maybe a good one. I am concerned about the break in procedure and getting the engine started quickly. M

You brought up a good point and there's several ways to skin that cat

Filling the carb bowl is likely the easiest, in my case the car already uses an electric pump. You can also "rig" a smaller tank even gravity feed, just be careful and "safe."

The greater point is that IT IS IMPORTANT with a cam break in, to get the engine fire quickly, with minimal fuss and worry

1...Make certain the cooling system is filled and bled. On a Mopar V8 pull the heater hose on small block, the one on the intake, or that same hose at the heater. Fill system, make sure you "have water" at the hose, and reconnect. Save a bit to top off

2...Get timing set CORRECTLY. You can set timing on the starter. I used to "know" that, Crackedback has pointed this out several times

3..Make certain automatic has at least a safe amount of fluid if it's a new unit. Same of course for stick

4...Make certain trans is in NEUTRAL (not park) and that wheels are BLOCKED

5...In general make certain area is safe and free from hazards, both physical, electrical, and flammable. If you are in a shop/ garage make sure there is actually adequate ventilation for you
