My 01 GT has 250,000 miles on it and I'm thinking of buying a crate engine. My only mods are a kandn cold air intake and steeda underdrive pulleys. I want my engine to have around 400hp when i get it. I want bigger cams, forged internals, etc. Where would be a good place to order it? I've been looking online and am having trouble finding SOHC 4.6L crate engines with the mods I want. Anyone know of any websites where you can basically build your own engine? Or have a selection of forged crate engines? Any help would be MUCH appreciated.
