23° OPEN ENGINES
The MRE 23 degree open engine has been a work in progress for us for many years in which has yielded great results. We have had great feed back over this time from top drivers to help us tweak and fine tune to produce a great product. What sets this engine apart is our “Outlaw” head package. We are able to make BIG power and keep the driveability. We have worked every avenue of this engine to make it run and drive better with keeping phenomenal reliability. This includes camshaft and rocker design as well as relentless manifold testing.
Some of the advantages a 23 degree engine has over lower valve angle headed engines is the weight of the engine. These engines are lighter than 18, 15, and 13 degree engines by 20lbs minimum. My thought has always been, if we can produce the power the car needs and get the weight advantage, this is worth pursuing. The driveability of these engines sets it apart as well. The smaller intakes and intake runners really helps from this aspect. Then lastly, they are cheaper to build than these other engines as well.
These engines work in open UMP type modifieds, NE modifieds, and Steel Block latemodels. We have this settup where you can choose and build what package you need. It gives you all types of options from choosing cubic inch, parts quality, and wet or dry sump.
