Default Header selection internally stock 429.

I just bought an AC with a 429. Has a Holley 750 on an Edlebrock intake. I am waiting on shipping so dont have the car yet but having some fun looking at things I know I want.

This is an under car exhaust setup and currently has cast exhaust manifolds. I would like to put headers on it and have been looking at options. I live in Florida and heat is an issue so Im thinking of wrapped headers to reduce under hood temps.

Heres the problem. I dont know who's kit this is and have no idea what style 429 header would fit best. Is there a standard header designs known to work and fit well?

I doubt there's much progress you can really make until you know what make replica it is - and actually have it to measure, work on, etc. Post some photos of the engine compartment, suspension, frame, etc. once you get it and someone may be able to identify it.

Most Cobras use side pipes, and I believe an even higher percentage of 385 series use side pipes. I can't recall the last time I even heard about someone with a 429 or 460 with under car exhaust - those have typically been Windsor or FE engines. I suspect you'll end up with either a custom built setup or, if you're lucky, find a set of shorty headers that will fit in the tight confines. Based upon my West Coast Cobra, Sanderson ff463 might fit, but that's only a guess. https://www.sandersonheaders.com/san...d-engines.html

I've heard too many bad things about header wraps to suggest such a thing, but many have had good success at reducing heat through ceramic coating. You may also want to put some insulation on the footboxes. There was a recent thread on CC about the kinds to use.

Good luck and have fun!

Mr. D,

I have to raise my hand; I have a 385-series with an undercar exhaust:

It's a ~2000 Everett Morrison. I'd guess every maker and also from year to year the shape of the headers can change enough to prevent them from fitting.

Sadly, when they started leaking, E-M (when they were in Tampa) rewelded them without bolting them to a head or a flat plate and warped them beyond redemption.

The car now has custom headers built by Sanderson which cost over $1700 ten years ago, modeled after the E-M headers - and they didn't fit! Sanderson admitted they'd never tried to bolt them onto a head It took a local 8-hour rework to get them correctly installed.

Oh, I did try to fit various ready-made block-hugger headers along the way. No joy. YMMV!

Having said that, you will probably succeed at finding/making a set if you take your time and apply some forethought and lots of measurements! Then again, my automotive experience frequently seems to include getting things wrapped around the axle...

When you are done, pictures, please!

Tom

I see some scary work on the exhaust and already plan to probably have to redo it. It looks like someone didnt have the right connection so used a big ass hammer to make it fit.

I would recommend ceramicoat headers and footbox insulation too.
GP Headers may be able to help out. You can look them up on the internet.
Good luck
