We offer custom designed and built high performance engines using the best parts available to include MRX Motors designed, exclusive pistons from Diamond, Venolia and Arias.   These packages are just a sample of the packages we offer.  We can build any engine to fit your performance and budgetary requirements. 

All of our performance engines have the following:

We qualify the entire block, which includes cleaning, degreasing, magnafluxing, sonic testing, stress relieving, and verifying all current measurements.

We machine the block to our tight specifications, which includes machining the deck, boring and honing with a torque plate, and line boring as necessary. 

We precision balance the rotating assembly, for best results, you should balance the flywheel and the pressure plate also.

The crankshaft will be ground and/or polished. 

There will be a full floating rod package with ARP rod bolts.  The rods are crack checked, shot peened for strength and drilled on the small end for improved pin lubrication.  Many of our engines packages include custom forged rods. With ARP bolts.

All new gaskets and seals.

Brass freeze plugs.

We use parts from Clevite 77 , Melling, Diamond, Arias, Venolia, Total Seal, Sealed Power, Eagle, ARP, Cometic, Brian Crower and of course parts manufactured by us or our manufactures to our design specifications.  

All brackets, housings, and fasteners will be cleaned, and painted because you can look good and go fast.

These specs are common to all of our performance engine packages.  You may customize these engines packages to fit your needs and budget.  Just give us a call.  Send me your good core engine to build and avoid the core charge.  All prices are subject to change without notice.

Due to the intended nature of use of race engines and their components there is no warranty. None are expressed or implied.

These are the most common engine packages we build.  Choose one of these packages or build your own.

Most engines are built to order.  Delivery dates for engine assemblies are approximately three to six weeks.
