Topic: Autolite Battery 70 Mach 1 351C

[Rbisch4]

Is there any situation where a Mach 1 with 351C had the 27F battery verse the 24F?

Yes, my understanding is that a '70 Mach 1 351C with A/C would have had the Group 27 battery.

428 CJ buildsheet that I have show a type "AF" battery installed in those cars. With and without AC Believe the "AF" is the group 27 battery.

351's from 1970 with AC show a "AD" battery being installed in cars with AC . Also installed in some non AC cars so likely the "up graded" battery choice that year and that application

Hope this helps

When I purchased my 70 Mach1 351C 4 speed car in 9/73, non AC which I still own today {unrestored} it had a group 27 battery in it. I believe it was the original battery as the car only had 19,000 miles on it. The battery still worked great in 1977 till I accidentally left the glove box open for over a week. It roached the battery. Wonder how much longer it would have lasted had I not had that misfortune ?
