what strenth battery for my compression?

I want to buy a lightweight battery (its going to say in the enginebay) and I see that a lot of them have a low rating of cranking amps. And I have 12.56 compression and I wanted to see what's about the minimum I should go in ca or in cca. I don't want to have jumper cables handy all the time. Thanks for any valuable imput.

My $.02. You may want to also take into account the starter. Even if you have enough juice to power it the starter may not be up to the task. Then again I don't know how strong GM starters are.

But to answer your question I'd get atleast 675 cca or more.

I can tell you for a fact, that the 6.0 starter cranks over with more power, than the F-body one, or the vette one. i know, I changed a few in one day, because I kept overtightening the electrical bolts, and they are very frail.

I like the Yellow top Optima...

You could always take your stock starter someplace & have them rebuild, and beef it up to crank out more juice.
