I got a hold of a 3500 upper, so I'm thinking of selling the 3400 stuff.
Because of finding a good deal on a 3.4, I can take advantage and use a 3500 upper (the 3400 was going to go on my 3.1).

I have a pair of 170 casting heads (from a 00 3400),
lower intake manifold with fuel rail,
3400 upper manifold/plenum.

I also have a set of 3100 pistons to make the conversion easier for someone who wants to make a hybrid out of a 3.1. (still pressed on rods).

I would like to sell it as a package, but may part for the right price. Any reasonable offers will be accepted, buyer pays shipping.
