Are these 340 ex-manifolds?

273 factory intake is no diff than a 340 factory intake in amt of perceived value...they are both worth something and maybe a little more to a #'s guy

You wanna bet? I have a REAL nice 72 340 intake. If I ever go to sell it, the damned bottom will drop outta the market for um and it will be worthless to everybody. Just sayin.
