Rare 260 RH exhaust manifold
http://www.ebay.com/itm/291047317870...witem=&vxp=mtr
Anyone ever seen a RH exhaust manifold with a straight down dump but TWO bolts, not three? It's like the common #5 shape, but on a 260 [ad says 350]...
I don't think that casting is in my extensive database.

No, I've only seen those turn-down manifolds with three bolt and an exhaust doughnut.
Those pictures are an excellent illustration of the often-discussed smaller intake tracts to improve torque and increase charge velocity at lower RPMs / intake volumes.

Well, upon closer examination of the ad's photos, it looks like an "8" manifold.
And, the PN Database says....
558319
MANIFOLD, Exhaust Manifold, RH, ID= "8"
1977?+ SBO, 2-bolt flange ~straight down exit, puny crossover inlet, looks like 260 or 307
Rare & nearly useless!
