And that is exactly why I ruled out the use of 318 heads exhaust and intake manifolds on the 360. And also why all LA cams, distributors, and carburetors are tuning issues not fitment issues. Rustyratrod said the same thing in a hundred less words. I guess should have left it at that rather than explaining the fundamental dimensional differences one will encounter when mix-mastering LA parts. Nobody in their right mind would install 318 heads on a 360 unless they were stranded in a desert somewhere or way down on their luck, and nowhere in my posts did I suggest doing so. I clearly stated 318 intake and exhaust ports were incompatible with the 360. Read my post #31 (intake and exhaust manifolds have bigger ports to match the heads). Furthermore hotairgypsy clearly asked in post #25 "i just want to know the proper year (of my block sic.) in the event i need any parts for it". No mention of performance or tuning, he only asks what parts properly mechanically fit his ostensibly stock 1978 Windsor 360.
