I'm into street rods. We use the same battery with the same class of engines as yours and don't have any problems. As you know, as the compression goes up, you gotta have more grunt from your starter and the Optima handles it just fine. Point of interest....we use a high capacity alternator (80+ amps) when we install an electric fan as the SBC orginial fan cuts the radiator to low for good cooling.
