2 1/8" Primary Headers
Please help me source some 2 1/8" primary headers for my 69 with 74 bbc engine mounts. The AFR315 fully ported heads need to breath. Thanks.

Re: 2 1/8" Primary Headers
Hooker Comp for Chevelle is 2in primaries and 3 1/2 in collector and fits our trucks sliding inside the frame rails. Should be fine unless you have crazy HP 800+..

Re: 2 1/8" Primary Headers
I have the hooker supercomps with a 2" primary and a 3.5" collector and are equal length, they fit pretty good for an equal length and they flow good...

Re: 2 1/8" Primary Headers
Has anyone had success or disaster with these in a 67-72 bbc 2wd, bb engine stands, with standard components up front? My preference is the first one.
Hooker Super Comp 2220HKR http://www.summitracing.com/parts/HOK-2220HKR/ 2265HKR Black http://www.summitracing.com/parts/HOK-2265HKR/ 2265-1HKR Ceramic Coated http://www.summitracing.com/parts/HOK-2265-1HKR/ You guys can debate the 2 vs 2 1/8 advantages, but I am past that. Both AFR and Dynomation indicate the 2 1/8 for my setup, and will be implementing N2O on top of that. Dont get me wrong, good discussion, but I'm stuck with a build in SD and a fab shop in CA right now. Thanks. Last edited by gene_ensor; 12-18-2009 at 09:06 PM. |

and does the collector hang down like right bellow the bottom frame rail where you would have enough room to bolt mufflers directy to them i have a very similar setup 72c10 big block and same heads and i came up with chevelle headers would be the cheapest way to get somthing bigger than a 1.75 " primary |

Re: 2 1/8" Primary Headers
To the O.P.,
you may try calling Tom Dawson Racing Headers. About 15 years ago, I had them make a set of 1 7/8 x 3 1/2 custom headers for my '66 with a sbc, and the headers fit like a glove. Tom used to be an engineer for Hooker and he would take a set of headers for a specific application, set them up in a jig, and duplicate those headers in whatever size pipe you want. I have nothing but good to say about them. Their shop is located in Nuevo, Ca. and their number is 951-928-0969. Good luck with your build!

Re: 2 1/8" Primary Headers
Hooker makes Super Comps for 73-87 trucks with 2" primaries, would that work for you?

Re: 2 1/8" Primary Headers
the problem with the headers "DESIGNED" for these trucks is that they hang down very low. The hooker #2455 work for me in a slammed 2wd auto with b&m shifter. 2" primary should be more than most need in a header, for everyone else $$$custom$$$
