Yes can be. But you'd need to rig/hook-up all that's needed to fire up & monitor during break in.
Wiring, coolant, ignition, gauges, among others.
If you monitor fuel mixture really well while in car, burning off exhaust won't be a problem (extreme exhaust temps).
Lean fuel mixtures during break in will cause that.
Once has TTI's glowing red once cause of lean condition.
Keep the mixture towards the rich side will help.
Just my 2cents here.
Best to you.
