Not every engine has to be an all-out race build to be impressive. 👊
This one is being built for a crew cab Silverado where reliability, drivability, and strong power were the priorities.
Build Specs:
• 4.075” bore LS short block
• Flat-top hypereutectic pistons
• Factory connecting rods with ARP rod bolts
• CNC-balanced OEM GM crankshaft
• Custom-ground camshaft
• Gromm Racing CNC ported 11° LS3 cylinder heads and a complete performance valvetrain
The bottom end is intentionally simple and proven. The real performance comes from the airflow. Those 11° LS3 heads move some serious air, and paired with the custom cam, this combination should deliver excellent throttle response, broad torque, and plenty of horsepower while remaining perfectly happy as a daily driver.
The goal wasn’t to build the biggest dyno queen—it was to build an engine you can drive every day, put thousands of miles on, and still have enough power to put a smile on your face every time you hit the throttle.
That’s the kind of engine I enjoy building.
