BobsZTwins Posted June 10, 2006 Share Posted June 10, 2006 While waiting to have the 4th cam installed (upgrading to full roller, tired of flat tappet cams failing break-in) I sent my left manifold to be recoated by Swain Tech due to spalling of the original coating. As luck would have it, they found a crack. If it weren't for bad luck.... Anyway, anyone out there have an old cast iron SBC manifold like the attached pic? It's an early 80's piece used on Caprice, Camaro, Monte, etc. I've checked out the local Pick-a-Parts, found similar but not quite the same. Tried eBay, no luck at all.

deja Posted June 11, 2006 Share Posted June 11, 2006 I bought my RamsHorn manifolds from Jerry's Discount Auto Parts. They aren't cheap but they may have what you need. http://www.jerrysdap.com/exhaust_manifolds.html Jerry's Discount Auto Parts 17320 Beach Blvd Huntington Beach CA 92647 714-842-0228 Quote Link to comment Share on other sites More sharing options...
Paz8 Posted June 12, 2006 Share Posted June 12, 2006 Try a different junk yard, that is a very common manifold, or take it to a CERTIFIED welder and have it fixed. Quote Link to comment Share on other sites More sharing options...
BobsZTwins Posted June 13, 2006 Author Share Posted June 13, 2006 Deja, I've got a request in for a quote from Jerry's, thanks for the link! Paz8, This particular version isn't that common any more. I've tried all the local Pick-a-parts and a few others as well as local engine builders and the only ones I can find have the O2 sensor bung. They're about and inch and a half longer. My crossover pipe is SwainTech coated so I don't want to have to cut/flare it to fit. Plus, the longer length interferes with the steering rod so I'd have to have the mating surface machined at an angle to clear. I have found one source for new ones but they're $130 ! ! I can get a header cheaper than that! Quote Link to comment Share on other sites More sharing options...
skipzoomie Posted June 13, 2006 Share Posted June 13, 2006 I have several old Chevy manifolds hanging from the rafters in my shop. I'll check and PM you. I'm in Orlando. Might help with shipping. Quote Link to comment Share on other sites More sharing options...
skipzoomie Posted June 13, 2006 Share Posted June 13, 2006 I have one of that configuration. Measured from the bottom of the down tube to the top of the manifold it is 7 1/2 inches. Quote Link to comment Share on other sites More sharing options...
BobsZTwins Posted June 14, 2006 Author Share Posted June 14, 2006 Skipzoomie, Thanks for the feedback! My old manifold is only 6 3/4". At 7 1/2" I think it will interfere with the steering shaft. That's the problem I have with the junkyard manifold I bought that has an O2 port, it's 7 1/2" too. Are you sure yours doesn't have the O2 port?

dr_hunt Posted June 14, 2006 Share Posted June 14, 2006 I've got a set of corvette rams horn, block huggers that would clear steering. Actually I have 2 sets, one is 2 inch outlet and one is 2.5 inch outlet. I'd take $50 for the 2 inch outlet pair, and $75 for the 2.5 inch outlet pair.
