Ok so my 2004 gt has a vortech t-trim and a recently found spun bearing. I could either waste like another 1000 dollars or get a short block. But I hear they are a bitch to install. Any info or suggestions on what I should do or shortblock to buy Im thinking about this one MMR-800 - MMR 4.6 Street Mod 800 (up to 800HP) 2V, 3V or 4V - Shortblocks - Mustang Performance Parts

but where did you have it tuned? Whats your fuel system like?
