    What's the thinking on high-flow mnifolds (like the rm horns) vs. long tube heders (I guess like the Throley tri-Y's).
    The thorleys are something like $500, but they are extra thick nd gurnteed forever I believe.
    The ram horns just plain look cool and will last longer longer than I'll be walking the earth.
    I'd be putting these eventully on 383 Vortec.

    TX,
    They have them on ebay. Do a search like this:

    Ram horn exhaust*

    put an asterick behind exhaust because someone may have misspelled the word. The asterick broadens the search to misspellings and plurals.

    PS, here is the set I just sold:

    I had ram horns on my K5and they were great due to the fact that I could run the exhaust under the oil pan right in front of the sump(Iv got single exhaust) rather than hanging down under the tranny.They cracked and I ended up replacing them with regular manifolds.

    Its my understanding that the Rams horn manifolds generate more torx at low rpm than will headers, info supplied by a Corvette Restoration shop here in Ft Worth.

    Still a very pissed-off

    I'm pretty sure not all "rams horn" manifolds are the "high flowing" (Corvette) type. I believe the diff is outlet, one being 2.5", others being 2.25" or some such. The outlet itself is in a better place, (central) but when comparing manifolds to headers, I don't think the rams horn are going to get you anywhere near the performance of headers. IMO, not worht changing from one style of manifold to the other, unless it is the actual header style manifolds GM did make for these trucks. (and that you can still buy, for $100's of dollars each)

    Why insist on counting when the ring gear has the tooth counts stamped in?

    I've got the stock '87 Corvette factory headers on mine. They dump straight down in the center of the head. Had to take abou 1/2 inch off of the trailing edge of the motor mount bracket on the drivers side to make them fit. Just something to be aware of when you start mixing and matching parts. [​IMG]

    Even if it is somewhat of a perforamce loss, I think losing all the BS is worth it. Less sealing problems, less underhood heat, and more room.
