How many feet of battery cable would you estimate for a 69 GTX? Just the positive running from the right rear of the trunk to the starter?

I do believe there is something called a 'tape measure'. It's a measuring device known to be invented some 100 years ago. Gee, way back in 1864 for the invention of the spring return tape measure; https://en.wikipedia.org/wiki/Tape_measure Thanks for the sarcasm but I'm sitting in a hotel room 1000 miles away from my car and I need to get the cable on order in the morning. I will buy extra but looking for feedback on other's experiences............

22 feet on an A-body, so maybe 24 ft for a B; That's from battery switch near R/R corner of car, up through existing drain-hole in trunk, along rt side crossing over behind rear seat bulkhead, running inside interior rocker trough, up through firewall to starter or power post. There's also the alternator-kill wire to plan for if you run it that way. Then there's the cable from battery (also @ R/R) to switch, which I usually buy pre-made, as well as the grounds battery/frame & engine/frame. Depending on starter access, you might want to run essentially a pigtail from starter to a plug for the starter wiring.

Keep in mind.. When mounting a battery in the trunk, that U also need to have a matching gauge ground cable secured cleanly to the frame. Many times we see a heavy gauge wire for the positive lead (+) and a smaller gauge for the negative lead (-). Also the final gauge size depends upon the total amperage load of all connected components including audio, headlights, fuel pump. If <75 Amps #4 cable is OK, if >100 Amps use #2 or #1 cable... Note that cables and terminals are available from Summit, Jegs or Mancini.. Just my $0.02...

Thank you!
I did consider running a smaller cable for the ground but right now am leaning towards same size for both. Might change my mind by morning.

I am on planning using bulkhead connectors.........

I would buy twice what your planning on using now and run the ground from the battery to the block as well as several other good grounds from the battery to the frame in the trunk area All the current from all batteries leave on the negative side and return to the positive side post, hence the need for good "grounds" The alternator current that charges the battery flows into the positive side of the battery also

After crimping the ends on, I might solder the ends too? Is that overkill? I am thinking it might help prevent internal corrosion? A proper crimp should not require any solder at all. Should be no air space for the solder to flow. Solder is less conductive than the copper wire... I weld nuts onto the frame front and rear. Frame connectors ad roll bars are good for continuity. Never had an issue. Same size wire for engine/frame grounds. One from block to frame, second from battery to frame, third is a floating smaller wire ground near ignition box/dash.

Solder and heat shrink is your friend for good continuity and protection My thoughts exactly No. 6 sided 12 ton crimp with properly sized closed end lug and proper crimper die then heat shrink. I know quite a bit about cable connections and grounding. I have been in many facilities around the world working on and correcting grounding issues in industrial facilities.
