With the rules change in 2012, we had to make some updates to our existing engine package. We really like the new changes that IMCA has incorporated. This will make these engines more durable without much added cost to the overall package. With the way the rules are written these engines will be very close in power from all builders (if motor is truly legal). There are a few advantages that MRE has to offer that separates our SportMod engine from the competition. The quality of machining we offer is second to none!!!

We start with a brand new GM block and completely CNC machine it. This allows us to get the decks and bores of the block in the exact locations to create a higher quality built engine and MAKE MORE POWER. We valve job the cylinder heads in a NEWEN CNC machine. This machine is only found in high-end Sprint Cup and IndyCar race engine shops. This allows us to put the highest level of performance valve job in the heads and keep it LEGAL. Our valve train knowledge from building OPEN and USMTS Modified engines that turn RPM levels well beyond 9,000 has been applied to this application. We realize these engines will not be turning RPM levels like this but the knowledge we have gained from the years of this have went into camshaft design and other valve train components to make the engine RPM better and the end result will create faster acceleration while being more durable.

We are in the process of making a video of a SportMod engine build from start to finish. This will allow you to see all the machining, assembly, and some pulls on the dyno. This will let you know how serious we're taking this program. I will list the parts used below. NOTICE we don't use any Chinese parts in the engine (WE LIKE TO USE HIGH QUALITY PARTS IN ALL OF OUR ENGINES PLUS I SUPPORT THE AMERICAN ECONOMY TO KEEP AMERICAN PEOPLE WORKING!) We build this engine with the mentality of building one for ourselves and we use as many AMERICAN made parts that the rules will allow.

When the rules will not allow full roller rockers and you’re limited to a roller tip only style rocker, it presents many issues with damaging the rockers or causing excessive heat to where it blues and galls the rocker arms to the point of failure. When the rocker is in this state, the engine is losing power from friction by 7-15 HP, let alone getting ready to fail. We have found remedies to this and thought we would offer it to racers who build or work on their own engines.

We soon realized you have to flood the rocker with oil. One way of doing this is TIG welding a shield on top of the rocker to keep the oil from flying out away from the rocker. This covers the oil hole and deflects the oil back to the pivot ball area helping with lubricating it and also keeping it cool. We do this for all roller tip rocker engines we build here, including the Southern Series SportMod where we run oilers in the valve covers as well. When only doing the deflector on the rocker (USRA B-Mod and Northern SportMod), we run a lighter valve spring than when we do on the valve cover option. When building the Southern SportMod engine we add the valve cover oiler option as well which allows us to run a more aggressive valve spring. Both valve springs are high quality and cost the same but one has more spring pressure than the other.

Valve Cover Kit		Work Done to Valve Cover		Valve Cover Kit Installed

MRE valve springs for USRA and Northern SportMod lighter spring for rocker deflectors only		$250
MRE valve springs for Southern SportMod heavier spring for rocker deflectors and valve cover oilers for pivot balls		$250
Add deflectors to comp roller tip rockers		$125
Complete pivot ball oiling valve cover kit Comes with all the lines and fittings needed and custom made valve covers to spray oil on the pivot balls. The valve covers come with an oil fill but we do not install any type of breather in the valve covers themselves (too much oil and will leak). We run the breather in the intake.		$495
We can also provide you with an intake and the breather installed. This is a $75 option added to our intake price, which makes for a clean engine.
