Braille battery?
 

Any good for a EFI car. 1 in front and 1 in rear. Any thoughts?

Although I don't have an EFI car, I've run a pair (1 in front and 1 in rear) of Braille B3121 batteries in my Stocker with very good luck. I try to replace them about every 3 years. You may want to replace them a bit more regularly in an EFI car. I learned that from Ken Faulk when I had a battery-related problem about 10 years ago.

The smallest batterys don't work with my setup. With FAST, MSD6AL, electric fan, water pump and fuel pump. I could make a run without restarts in the lanes, scales, etc. If I had to restart several times, I sometimes had to get a tow back from the scales. this was with 1 battery. Even the 21 lb battery was a question. I have since gone with a regular 450 AMP battery for the extra 10 lbs. Also; nothing against Braile. but East Penn Powersports batterys are much cheaper - available on line or at Walmart and sure look and act the same!
