what size battery

[Jarred Hodges]

I bought a new battery for my truck about a year ago. It developed a bad lifter tap so it was parked and I put the battery on my racecar since it fits perfect. I plan on buying a new battery in a week or so. I was hoping to get away with the $50 battery which is 540cca. If not I will go with the $75 battery which is 900 and something cca and is huge. I have a basically stock 390 in my truck

the battery size is either a 24 F or a 27 F

I always get the biggest CCA rated battery that will physically fit.  To me it's a little added security in the middle of winter, to know she'll crank over good when it's below -10*.

Right now I got a 900-some cca battery in the truck from Walmart.  Some people say they are junk but I never had any problems with them.  Got around a 300 amp battery in the lawn tractor, could probably jump a car off that !!
