I have the Optima "Orange Top" battery in my car. Battery model # is R34. Part number is 8003-151. They're a little difficult to find, as opposed to the "red top" units which seem to be everywhere. The orange tops are necessary in some of the cars which mount the battery underneath the passenger side fender, because the positive terminal is reversed in location from the red top. The pole orientation on the orange tops allows the positive terminal to be "hidden" underneath the fender. My literature shows MCA = 980 amps @ 32 degrees; CCA = 750 amps @ 0 degrees. It turns my 427 stroker over like a top. You won't be disappointed.
