How to identify yours

Match castings before you order. The listing gives engine VIN code J, block castings 093, 737, 089, 227 and 150, head casting 234, and crank castings 981 and 268. The casting location is the driver side of the block. Note that the important notes on this unit read Block Cast #227, 150 and 253, so 253 appears in the notes but not in the block casting list. Call 216-250-6666 or email sales@varietyengines.com with the numbers off your own block and heads.

This is a remanufactured exchange unit with a 6-month limited warranty and a possible refundable core charge. See the remanufacturing process and warranty pages.
