charles, all answers are pure speculation & personal opinions, including my own.
I have for many years believed that the cheepest 525 cca battery that I could find was the answer for me. They have cranked any/all of my vehicles that I have installed them in for 40 years. I had to replace the one in my pickup earlier this year. I wanted another Advance Auto like it because the guy looked up the code and declared the old one was 9 years old.
I figured if I can crank my car/truck for $10-12.00 a year I'm happy.
There will be others that will suggest that the most expensive 6-8 year battery is the only way.
It's a choice that you will have to make.

1967/79 F100/350 as original: Group R-22F = 45 amps / Group R-24F = 55 amps / Group 27: R-27F = 70 amps; R-27FA = 80 amps.
Make sure the new battery you buy...has the positive and negative terminals in the same location as the old battery.
AMC/GM/ChryCo batteries have a G suffix: These batteries have the terminals reversed. So if you don't notice, you'll hook the battery up backwards, and it won't be too long before it goes dead.
R-22F's were only installed in F100's with I-6's. Most 1967/79's came with R-24F's, the R-27F & R-27FA's were optional, except on Camper and Trailer Specials. These came with either the R-27F or R-27FA.

You are in warmer climate, so a big battery for starting isn't such a big deal as it would be in colder climate. Heat is just as bad for a battery, but likely won't be fighting to start a -20* engine.
Even the best big dollar versions fail. I stick with middle of the road stuff. I used to always have Diehards in my vehicles for many years.

Don't get hung up on brands, Johnson Controls, Exide, & Purolator make prolly 95% of all batteries sold & used in this country.
