Have a 1998 K2500 CP6 option. Just installed a custom built SBC Stroker 7.0L dart block AFR heads. dyno'd at [email protected], 560ft/lbs@4Krpm torque curve is awesome ; [email protected] to [email protected] should pull future trailer with no issues except never passing a gas station. It should provide a significant upgrade from 5.7L OEM. Still going through the pains of getting a tune that runs for daily driving and towing. Black Bear Performance has been very helpful. Cold start is awesome now but still a long way to go for daily driving.
