Does anyone know who makes a traditional 3 carb (three 1 barrels) set up for a 230/250/292 Chevy inline six. I have looked in all the usual places and came up with nothing. Might be they don't make one for this Chevy engine model. Also, any idea's on aluminum valve covers, aluminum lifter covers, aluminum air cleaners, performance cams and split exhaust setups and so on would also be appreciated. Thanks Specs
performance engeneering makes lifter gallery covers that were pretty economical, maybe valve covers too. if you get a used intake look for a heated one. don't do what i did and have to mill out a heat box. if you get a older aluminum valve cover look for a baffle in the pcv valve local or be prepared to make one. i am kind of partial to stovebolt engine co and clifford too. good luck.
There used to be almost 20 manufacturers making this stuff, some is still on eBay especially Offy and Clifford. The usual choices are the original Rochester, Carter, Stromberg, Zenith etc. 1 bbl., but use smallest ones you can find (the Rochester B off a 216 or a 194 is a good choice)
Offy makes (or did make) a triple single-barrel carb intake that fits those motors. I know, 'cause I've got one. I think the MerCrusier cast aluminum valve covers for those motors (as used in Mercury inboards) are pretty cool if you can locate one. I would expect a used one to be much cheaper than an Offy, etc. A fellow had one on a car at the HAMB drags a couple years back. Said he found a couple of them in a boat dealer's back room for like $30 each. Don't forget, the 292 side covers are different from the others (6 inches tall, instead of 4 inches). The heads can use all the 250 stuff, but the block is a different animal.
The marine covers are getting harder to come by ,But they are still out there. As for cams the are many companys who make them for our L6s.

Looked for the old school stuff for my 6 cyl, hard to find. Went with the Stovebolt cast iron headers, offenhauser dual single barrel intake, but I built some mounting plates so I could run two Rochester 2g, 2 barrel carbs in place of the two single barrels. Got the finned valve covers off of ebay thru Summit Racing, their not cheap, add on ebay said fully polished, received them, the divets on both sides of the valve cover were not even sanded smooth, sent a email to summit, bitched about the fully polished as stated in their add, they refunded me $45.00, just polished them myself, speedway motors at one time had the offenhauser 3 single barrel intakes. Good luck in finding parts.
