I HAVE A COMPLETE (LONG BLOCK) LS1 5.3 ENGINE THAT WAS PULLED OUT OF A 2004 CHEV TRUCK. THE ENGINE IS IN NEED OF A REBUILD. THE ENGINE WAS PULLED OUT DUE TO LOW OIL PRESSURE AND LIFTERS MAKING NOISE. DID NOT BLOW A ROD OR ANYTHING OF THAT SORT. WOULD PREFER TO SELL AS COMPLETE BUT I'M WILLING TO PART IF NEEDED. WOULD LIKE TO GET $350 PLUS COST OF SHIPPING. WOULD PREFER PICK UP. IM LOCATED IN WEST MICHIGAN.

I thought that LS1s were 5.7 litre?

they are lol maybe an lsx??
