The 454 in the Stepside isn't running all too great lately. It's a standard bore Gen V 454 block with some e-bay aluminum heads and a hydraulic roller cam from a ZZ502 with solid roller lifters. The engine was an assembled running unit I bought and swapped in without doing anything but adding my old Holley carb. I checked and have adjusted the valve lash once, but it needs some other attention now. | Big Trucks Low Bucks
