i dont know if you can get a block from a 3v GT still or not, last year woulda been 2010 I think. Theres nothing wrong with a good seasoned block though and you can find the 3 valve 4.6 blocks much cheaper than the Teksid blocks typically, the 3v block is the strongest aluminum 4.6 block.

I dont believe there are any 4.6 high performance shortblocks available from Ford, I think theyre all set up to be closer to a 5.0 now and seems they have issues with head gasket sealing at high boost.The pistons in those shortblocks arent the greatest either, from my understanding theyre like the aluminator/terminator motors and tend to break a ringland if you have any detonation where an aftermarket piston like something from Diamond is much more robust. When I had to rebuild my aluminator we went to a diamond piston for that reason (both tuner and builder agree in separate conversations)
