Check out our all new stripped down LS3 6.2 motor from GM – it’s a blank canvas for your classic car or truck!

Karl Kustoms GM LS3 6.2 Motor Specs:

It’s the same LS3 6.2 motor as before with a nodular iron crankshaft, powdered metal connecting rods, hypereutectic pistons, and LS3 cylinder heads. However, unlike the other LS3, this stripped down long-block version is set up for older cars and trucks. This engine delivers 430 horsepower but is available in 495 and 525 horsepower applications.
