I'm with Doc on this. When (not if) the pickup coil in that 48 year old HEI fails your done. Time to pull the distributor and completely disassemble it to replace the coil. Hopefully you have a spare HEI stashed behind the seat.
Or more a likely scenario is losing that key fob for that late model car while on that road trip. Be prepared for a tow to the dealership.

I'm seriously considering one of these for my 72 Firebird. Once you price out a rebuilt distributor or a quality new one, an aftermarket ignition system with a Rev limiter and retard contols, a distributor gear for a bilet roller cam, the cost of having a professional distributor curve done at least once, the cost is the same or better without the ease of adjustability.

And if your worried about losing your phone get an old cheap phone, load the program on it and hide it in the truck. It doesn't need to have service, just Bluetooth to undo the ignition lock.

Just my opinions. With them and five bucks you can buy a cup coffee most places.
