I am looking for a reman long block for a 2001 Jeep Cherokee for a friend of mine. The 0331 Head cracked and he wiped out his bearings and he want's to put a reman engine in with a nice warantee. Where can I get a long block with and alternative to the 0331 head? I found plenty with the 331's but can't seam to locate any with another casting. I seam to remember reading somewhere where there available but can't quite remember. Thanks!!
