I have a upper and lower intake that I bought that has been welded and drilled out to use with 96+ vortec heads. They also are both fully ported The guy that I bought them from said Mccoy motorsports did the conversion. I paid him $550+shipping Then I sent both intakes out to be professionally ceramic-coated. that cost me another $3oo+shipping. There is absolutely nothing wrong with them. I am just going a different direction with my build. I will sell them for $750 shipped Thanks
