What's Included in a Long Block? What is in a long block can vary. The minimum parts installed in a long block package would be the block, crankshaft, rods, pistons, heads, and usually the camshaft and valvetrain. So, everything in the short block plus at least heads and usually the valvetrain including the timing chain. Sometimes you get a timing cover, valve covers, balancer/damper, and oil pan, but oftentimes not. This is a great option for someone who knows engines but has little to no experience building one. With a long block, all the hard work is done and the buyer only has to be concerned with choosing the right accessories and getting the engine installed in their machine. Ask our sales team what's included in the long block that you picked.
