Which Headers to go with?!?!?!

Sorry but that makes absolutely NO sense. With Tri-Ys you don't have exhaust manifolds anymore as they replace them. Tri-Ys were on every 65/66 Shelby and most of those were manual transmission vehicles.

I thought the same thing before, but there is a difference from standard to hipo z-bar configuration, but have not actually tested clearances with the hipo version yet. I am running tri-ys and the stock z-bar linkage on my 1966. The lower portion of the z-bar near the adjusting rod pin will just hit the tri-ys, but this was easily fixed by cutting the "corner" section off near the pin, still leaving enough material for strength. Fits and works fine now.

With any long tube headers you have to relocate the power steering ram. Doesn't matter what brand of headers it is. The added length of the relocation bracket puts a LOT of strain on the frame rail. It is not uncommon for the bracket to pull loose from the frame rail due to the extra strain.

Not true, i have hooker comps on my 351w and the drop bracket is not needed. This seems to be the case with most 351w motors due to the increased deck height, but most 289/302 motors with headers seem to require the drop bracket.

Do you have a manual trans? The catalogs that sell the tri-y have a comment about them not fitting with the stock manual trans z-bar. I beleive I saw a Doug's header that is tri-y configuration, but goes around the z-bar.

The generic Tri-y's usually dont fit C-6 or AOD automatics. Though the Doug's may.

I am thinking of using this company for my 69 fastback with a 351W, C6 auto tranny and a Randalls Rack and Pinion, nice thing is that they have experience with the Randalls rack and know how to work around it, as well as understanding the difficulties of getting around the C6. I bet they would have some good info for your setup as well as he told me they are not premade, but rather they match them up to whatever cylinder head you are using.
