I'd scanned many companies now that offer short and long block for the 4.6. I'm manly interested in the big bore versions my self. VTengines offers a short block for $3999. and a Long block for $9500. Using billet this, aluminum that, and forged items. Now, my 96 GT will never see boost, or the juice. What kind of parts, barely above better then stock, can I use? and how much cheaper is it to buy all the parts and just install your self? What specialty tools would be needed? If I had the knowledge, i'd build my own big bore block, with a bit better then stock parts. I just need the know how.
