* Cores must include usable block, crank, cylinder head, oil pan and bolts, pickup tube, timing gear housing, timing gear housing cover and bolts, rear seal housing and bolts, piston cooling nozzles, and bolts, lower rocker box and bolts. Injector wiring harness and bell housings are preferred so the engine stays sealed in shipping. If there are issues with any core part you will NOT be charged the full core amount, just the amount to replace the bad part. Our core charge is based on re-manufactured parts.
