HEMI Engines & Engine Parts

Get everything you need for a new high performance engine for your HEMI. Whether you are building a naturally aspirated motor or forging the bottom end to get it ready for boost, you can find everything you need here! We sell whole crate motors, long blocks, short blocks, and even individual engine components. There are various platforms to choose from as well, ranging from the 5.7, 6.1, and 6.4 blocks.

HEMI Heads & Cams

HEMI Intake Manifolds

Intake manifolds are the final step before the intake charge enters your Cylinder Heads. Both the stock head castings and intake castings can be extremely rough causing disturbances in air flow. We create performance gains by opening the inlet to the manifold, the runners are smoothed to reduce this interference in air flow, and finally the port matching the cylinder head.

HEMI Long Blocks

A long block Hemi upgrade comes with a high performance forged rotating assembly and valve train (ported heads, camshaft, etc.) already installed. We carry 5.7L, 6.2L, 6.1L, and 6.4L (392) based long blocks. Custom long blocks are a perfect base for a truly awesome high performance HEMI build.

HEMI Rotating Assembly Parts

The rotating assembly is the heart of your Hemi 5.7, 6.1, or 6.4 based power plant. Upgrade to high performance forged connecting rods, pistons, and crankshaft to ensure durability and increase overall performance. These upgrades will give you the ability to safely add a supercharger or turbo charger to your vehicle.

HEMI Short Blocks

A short block Hemi upgrade is perfect if you already have all of the necessary parts to complete the motor. A short block comes with high performance forged rotating assembly already installed. Hemituner Performance offers custom short blocks made from a 5.7L, 6.1L, 6.2L, or 6.4L based HEMI block.

HEMI Stroker Kits

Stroker kits include everything you need to upgrade the bottom end of your Hemi engine. This includes high performance pistons, connecting rods, bearings, piston rings, and a forged crankshaft. These kits are perfect if you’re looking to rebuild a motor or get your Chrysler, Dodge, or Jeep vehicle ready for forced induction or nitrous.

Other HEMI Engine Parts

If you need replacement gaskets, bolts, new main / head studs, or any other miscellaneous HEMI engine part, then you’ve come to the right place. We have everything from Mopar OEM replacement parts to full on Cometic top end kits. Add some extra security to your HEMI with new ARP main and head studs!
