[QUOTE="ANGREY, post: 16665322, member: 188865"] Porting GT (mustang) heads isn't really sensible given the 350 heads. A set of fairly aggressive ported GT heads flows about the same as the base 350 heads. One would be better off to just buy 350 heads and a 5.2 block, which can be done for only slightly more than the head work on 5.0 heads. Swapping cams to a CPC set costs a little more, but I'm assuming anyone who's porting the heads would be doing that anyway so the cost there is a wash. Even my standard size valves in my 350 heads (ported) flows 380, which blows the doors off any set of 5.0 heads. The 350 heads just start off a bigger platform. I'd love to see a max effort 5.2 build with max cooling (killer chiller or methanol kit) to see how much power could be wrung out, but as others have pointed out, we'll probably never see it because it'd be significantly more expensive than just adding a stage 1 kit and perform markedly less. If I had to venture, I'd say a max build (CJ, cams, port and polish with upgrades to valvetrain, headers, exhaust, methanol injection or killer chiller) could probably see 570-580 to the wheels if revved to 9k on E85 and max timing with cool air charge. That would equate to about 640-650 at the crank. Over 2 hp/cube. While it would be impressive, it would be akin to a $500k double wide, upgraded mobile home. Sure it's nice, but one would be better off just buying a $500k new deliberate home. [/QUOTE]
