It's only available second hand now, in their infinte wisdom MP killed it off/discontinued it. The good side of that is: now nobody can complain they are too expensive as they did for decades They had a high price not only because of profit but because they were cast and machined in California. Oh well, that ship has sailed. Rich H. Esse Quam Videri

moparx "Butt Crack Bob" Joined: Sep 2003 Posts: 19,355 north of coder	i have heard of the restrictive passageways almost from the beginning of the reproduction housings, but i have never seen a comparison side by side. i have an unbranded housing here, and it seems to have bigger passages than a couple of iron housings i have to compare it to. anyone have a restrictive housing to show the problem ? TIA as always !
