The RJM USA Closed Deck Block is designed to give you the best platform for reliability and sustainability regardless of your power levels. Our closed deck blocks are designed to allow for better heat transfer to the outside of the block while also creating a more stable and rigid structure for your rotating assembly. This reduces the wear on your cylinders and when combined with our Dry Sleeves from L.A. Sleeves you have a bulletproof block that is good to 1200whp+. All machining is done in house on our 5 axis CNC machines. The blocks come with a factory Bore but optional Plus sizing is available for an additional cost. Please Inquire if you want to have the optional Dry Sleeves installed or want the Optional Over bore.
