I hear alot about these and people say they sound awsome with glass packs....The problem is, is that everywhere i see someone mention fenton is for a ford inline...Does anyone know if the fentons work with chevy's. I have seen it on a GMC. Where the hell do you get these things?
The Fenton company, way back made cast iron headers for just about everything at one time. Today a company, Patrick's in Casa Grande AZ repops the Ford Flathead V8 and Chevy inline 216/235/261 headers. I'd check with Langdon's Stovebolt, ad runs on the top of this home page. I don't believe Patricks has a web site, but you could run a search. There are other companies that make or 'split' duals for Chevy sixes also.
Best of luck
Hi Jason . . .
For an inline Chevy you have four choices for dual exhaust:
1) The 'old school' conversion of a stock manifold to dual via welding. Almquist used to sell the additional flange and instructions for the conversion. Manifolds that have received this treatment show up on Ebay now an again. There is one out there now.
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=2485161671&category=34203 2) A cast iron header like the original Fentons or Tom Langon's new design.
http://www.patricksantiquecars.com/cfentonheaders.jpg http://www.stoveboltengineco.com/acartpro/product.asp?productid=89 There are lots of sources for Fentons including Patricks, and Obsolete Chevy. Fentons seem pricey compared to Langdon's.
3) Short tube headers - or what California Bill calls 'Clark' sytle headers. There are several sources for these -- including a place that will ceramic/powder coat their work.

I would add another option which is having your own exhaust manifold modified, which permits keeeping the heat stove intact. Our friend Mike Yoder at Kansas Kustoms has done hundreds of "split jobs" and his work is excellent.
Here is his contact info.
here is a question. Why do they use the exhaust to heat the intake? Is this to keep the fuel vaporized? I know with fuel injection you want cold are but most fuel injection is dry manifold so they dont have to worry about condensing fuel...since we are talking carbs it is harder to keep the fuel vaporized....What are my options to help with this if i go with a header?
u can get a tube welded on to the intake along its entire length and have the hot water running through it...very simple to do. although i dont think a heated intake is necessary...as far as i know the heated intake is for economy, if u want more power then run it cold....i dont think its too much different with the concept of cold air induction for caberated or fuel injected...so if u go with a header dont worry about anything...if u notice poorer performance, then its no problem to weld on the tub and change the hoses a bit.
Jason, Go to "TECH TIPS" in the blue menu to the left and read Tom Langdon's Intake Heat article. As you probably know by now Tom Langdon is "The Stovebolt Engines" company and one of the many
more knowledgeable and helpful members of Inliners.
