I say sell the whole thing for about 2750-3000 and all the new stuff if you part it out,sell them for what you bought them
for or close to it.

the block I would sell for 300 by itself
the head 200-300 itself
the tranny 400 by itself.just to give you an idea.

look around and see what other sellers are selling similar items for.and base your prices from that and your own judgement as to how much its worth.good luck with selling everything.
