OBR Remanufacturing Process
OBR's remanufacturing process begins with a used engine core that is completely disassembled, cleaned, and inspected. Components are checked for condition and specifications, and parts that do not meet requirements are replaced during the remanufacturing process. OBR long blocks are assembled with the cylinder heads installed and timed on the short block and are built to meet OE specifications.

There is no additional core charge added to your purchase.
Core return paperwork will be included with your order. If your original long block is returned and passes inspection as an acceptable rebuildable core, you may receive a refund of up to $300. The final refund amount is based on the condition and acceptance of the returned core.
