for a 454 with a MILD cam. cam is basicly one step up from stock. ill recheck all of my connections and plug wires, engine is getting gas and turning over but seems to be turning over slow. reason i ask about cold cranking amps, this battery is charged and came out of my 2002 silverado 2500 hd 6.0L and was in the truck when i purchased it used. i was told that the battery that was in the truck (now in the camaro) did not have the required cca for the truck. with a bigger motor in the car, wondering if the battery doesnt have the juice required?
