exhaust manifolds

[Sinister68]

I've been searching the internet and decided I'm twin turboing my 68 Plymouth. The problem I'm having is I need to get exhaust manifolds for a small block that I can mount the turbos up to. From what I've found I have to have them custom made. Is there anyo e here that knows where I may be able to get this done or how to go about it. Unless someone knows where I can buy a pre fabed set

Aaron Brucker just got his CNC plasma and I'm sure if you brought up a set of stock headers or just the gaskets for it and he could draw them up in CAD for you and cut them out. I think his shop rate is $80/hr, but I can't say when he'd be available or

That said, I would be surprised if there wasn't an existing set out there. A quick look dug up these.... no idea if they work but its a start...

Honestly though, getting the header flanges bought/cut might be the easy part of that fab job, but I'm sure it would be fun when you are done. Let us know what engine it is and I'd be happy to do some more google fu for ya.

Its a small block 318 with a cam, double roller timing chain, weiand action plus intake , holley carb, milled heads, new valves etc. Others more I'm drawing a blank though.

So is it a different bolt pattern/style then what I posted above? I guess I ask because typing in "small block 318 header flange" into google gives lots of results but I guess I'm not sure if yours has a specific variance from the norm or something.

Not sure how much the 318 changed over the years but the 318 Jeep ZJ exhaust flanges match with the Dodge (and Jeep) 5.9L 360.
