The parts needed to bolt a gen III or gen IV "LS Style" motor into your 1973-91 4x4 truck/SUV

The first item on the list is our HD high clearance engine crossmember and competition motor mounts. This will give you the strength needed for the added power, plus room for uptravel from your suspension. No low hanging things to hit your diff on here!

The second item is the adapter plates used to connect the "LS Style" block to the competition motor mounts.

For the third item on the list we have our VSS mod if you are running a np205. This give the ability of an electronic speed sensor reading instead of the mechanical. Needed with many of the modern transmissions.
