$2200 picked up in Bowling Green, KY for the shortblock.
As for the longblock will be everything listed above plus: 6.0L "317" heads (with 70cc chambers so the actual cr is 12.2 to 1) that were ported and polished by me; nothing special and left the stock size valves with a 3 angle job in them with patriot gold .650 springs, Lunati pushrods, GM 6.0L mls head gaskets, new GM lifters & lifter cups. The oil pan, timing cover, timing set, and oil pump will not come with the longblock.
