413 max wedge cast iron headers

[Gary Stavely]

Hello I have a set of these available to me, wanting to use them on my 67 383 coronet. I really like the look of them has anyone ever installed these on a 67 coronet? If so are they a direct fit? I will have to have the rest of the exhaust built either way and I will probably get them ceramic coated.
Thanks in advance!

67 383 4 bbl, mild cam, 915 heads 1.60 exhaust valves.

Mine are in a 62, but I like them. I think they should fit in a 67 without issues, but someone may know more about this than me.

Reproductive, or original? Original Max Wedge ports may be different.

Original i think he may have had them on a 440 last but not 100%.

65 and earlier cars had the engine mounted about 1 1/2" further forward, those manifolds sweep pretty far rearward I think you could have clearance issues with the firewall...

Not saying it won't work but I've never seen it done & I've been around this stuff for at least a few years.... lol..

FWIW those manifolds are pretty desirable & if you can buy them they could be swapping material for other parts you might need...

If they worked on a 440, they will work on your 383, especially with 915 heads.

If you want a little more performance, move up to the 1.74 exhaust valves.

A B block will sit a little lower and that may help in clearance issues. Like you said they are desirable and I would snag them if they are reasonable.

Those manifolds on a 383 with 1.60 exhaust valves is akin to putting slicks on a stock slant six Belvedere.
You'll look cool but that is about all.
If you owned them, the $$$ from selling them would afford you some real nice headers that would fit for sure.

Thanks! I think if I move up to a higher compression pistons I may open up those exhaust valves, the engine was a 2 bbl originally.

Lol, I am pretty sure they would work ok but I know what your saying. If anything I will go with a hp exhaust instead, I kinda want it to look fairly stock

After seeing what they are worth i would buy them off him in a second for what he wants. Problem is I think he just thought they would be cool to throw on during the restoration if they fit, we will see though you never know but I am not really into the parts selling business.

 

[Don Frelier]

I've seen them on a mid late 60's mopar before.
I think they are awesome.
You would likely need a heat shield on your master cylinder, may not work with power brakes.

You can check what they originally came on by checking the casting number on the TTI site.

Jerry, I wish they were ‘reproductive’ ...since the originals are pricey pricey pricey!!

Perhaps let him know what they are worth & offer to help him sell them... An ad here on FBBO is pretty painless & I'm sure someone would be interested...

Actually the fella restoring my car owns these and we thought about putting them on but I think I will go with the hp manifold, I must have misunderstood when talking to him on the price because yes they are pricey lol.
