MRE is now offering fully CNC machined Dart LS blocks. This way a person can get a fully machined block, all to their specifications, all from one place (keep in mind, out of state customers do not pay sales tax). All the machining done to the block is performed on a new CNC machine. This way your decks, bores, lifter bores, etc. are machined in exact locations. Our prices on the blocks are very competitive since we do such a high volume. We stock over 100 Dart blocks at all times. We also offer more advanced machining operations that only a select few shops have these types of capabilities (we are the only shop that can lighten a Dart LS block). Listed below are prices laid out from buying block “as is” to having a fully machined ready to assemble block, then below that are the more advanced custom operations.
