After my removing of the second battery in my dart cos it was 11+ years old, I went w/a 1000 cca single battery and as before my 60 ft suffered from a 1.33 to a 1.40 so, can any other battery w/less cca's be added w/out issues or do I need a duplicate of the other...........
Well, when we finally get a good run on our first low deck in my car, I will let you know what a good 60ft is...Best with the 440 based was a 1.329 with my pre Thumper carb....
PS we like the red top 900cca battery's. I use just one in each car...But we do use a full size chevy 1-wire alternator.
Also, I spend as much time tuning the front suspension as the rear...This is even more important on a leaf spring car.
