'71 Chrysler LM 318. Wal Mart lists batteries from 500 CCA to 800 CCA for a '71 Dodge 318! I'll guess that 500 is the minimum and anything above that gives you more cranking time? Looking for the battery size others are using.

DO NOT USE A WAL MART BATTERY!
Get the highest CCA you can find that will fit in your battery box.
I know that you have not mentioned this...... but if your concern is being able to have enough reserve AMP Hours for cranking.......... and if by chance your starter motor is in need of replacement, I'd suggest replacing it with one of today's HTGR/PMGR starter motors.
The HTGR/PMGR motors require fewer AMPs for the same cranking task, of which means that your CCA capacity does not need to be 800.
Food for thought!

This works for me................

Know nothing about today's starter motors. Thanks for the info. Pulled my starter and alternator last year and had them bench tested at an auto electrical shop. Wish I had known about new tech starters. I suspect mine is older.

I thought "highest CCA" might be the answer. Curious about your comment about Wal Mart. Have used them for years in my cars/trucks. Must say though I have never had one last beyond the 5 year warranty period. For $102 I can get an 800 CCA with a 3 year full replacement and 5 year pro-rated warranty. On-line I didn't find anyone talking about their warranty.
