CCA Ratings

[NJSHO]

Does anyone know what the min. CCA rating for a battery to start the SHO would be (assuming the engine has stock compression?) I drive my car every day in the NJ winter but I want a light weight battery that will work year round. I found one that is listed as an "all-season" and it has the following specs:
Pulse Cranking Amps: 1067
Cranking Amps: 574
Cold Cranking Amps: 425
Amp Hour Rating: 21

i have a hawker odyssey pc925 battery, 925 cranking amps i believe and something in the 300 range for cold, i dont drive my sho in the winter so i cant comment about cold weather but in cool weather mid 40's my car turned over fine.

I think stock is 660CCA. I wouldn't go much lower than that. There is no worse time for your car to not start than when it's 12 degrees out.
