I'm waiting on a buddy to get off of work to ask him specifically about that block. I've heard some Teksid setups going for $2000+. I, personally, wouldn't buy from someone that only took Money orders for payment. I like a bit of the "security" with paypal and my CC.

 

Sean Highland wants 10K for a Teksid longblock with forged internals for the 2005/2006 GT plus your block as a core. My bet is he is NOT supplying a NEW Teksid block either. Bet is it is rebuilt.

 

You can do the same thing as SHM is doing. I've thought about buying a 98 Mark motor, which I found for 300. Remove the 4V heads, manifold, etc. etc. and put them up on Ebay. Should be able to recover some of the cost there. Now throw in Forged Pistons, Billet/Forged Rods, and a Forged Cobra Crank. You need a few other things, but you are on the way to a built bottom end.
