Battery Group Size

[mikester]

So looking at a few Delco batteries I found the group 78 has 960 CA compared to 875 CA with the group 75. Looks like its going to be the 78 since theres enough room in the tray. I was surprised to see the Delco AGM in group 78 only has 740 CCA and 890 CA.
Again, you guys on this forum are the best !!

I use the group 78’s in my cars. I actually have the same battery in my 2006 2500 suburban, my 70 ss396 chevelle and the 80 Malibu.
