Here is the email that Doug sent me about the Dutra Duals back in 2005...

"Here is some general price info. on my "Dutra Duals" cast iron exhaust
manifolds for the Slant Six. I currently have manifolds in stock so you
can
order a set directly from me. (Im not sure if he has them in stock right now, this was back in 2005)

The different prices listed below apply to the different levels of
manifold
completion. (manifold type and machining)
You can save some money if you do some of your own machining on the
front
manifold. (hole drilling and tapping) and modify your current factory
manifold for the rear section.
As you will see below, I can also furnish you a complete, finished
set of manifolds at a higher cost.

$180 for a new, semi-finished "Dutra" front casting only.
The "semi-finished" manifold has the two main surfaces machined flat
but it does not have any holes drilled or tapped.
(basically a raw cast iron manifold with 2 surfaces ground flat)
I do not recommend getting the semi-finished casting unless you are a
machinist by trade and have access to milling, drilling, tapping and
grinding equipment.

$225 for a finished front casting, fully machined, ready to install
"Dutra"
front manifold, you will have to make-up your own rear manifold section
as
outlined in the "how to" article posted on the internet.
http://www.slantsix.org/articles/exhaust-man-mods/exhaust-manifold-mods.htm

A complete finished manifold set (front & rear sections) costs $350.00
+ a
factory exhaust manifold "core". This gets you the pair of manifolds,
ready
to install.
($225 + $125 for me to machine and weld your "core" factory exhaust
manifold
into the modified rear section)

$430 for a complete, finished set, *no core provided by you*. This
applies
to either a "carb heat" style" manifold set or a "Dual Dutra Duals"
set-up.
($225 + $125 + $80.00 core charge) or $225 twice, less $25.00
"discount" for
buying two new fully machined Dutra castings. (Dual Dutra Duals do not
allow
for carb. heat or auto. choke mounting and will need two new exit pipes
made)

The Dutra manifold outlet size is 2 inch and making the new head pipes
out
of 2 1/4 exhaust pipe works well. A "Y" system can also be made by
using
two, 2 inch head pipes and "collecting" them into a single 2 1/2 inch
system
with a large, free flowing muffler. A system like this should be made
up by
an exhaust shop and can yield a 8 to 10 % performance improvement and
have a
mellow sound.

I have more options for making custom modified rear manifold sections.
These apply to special intake manifold set-ups like the triple Webers,
Lynx
SU Carbs or Hyper-Pak intake manifolds.

As I noted, you can order a manifold set directly from me by sending a
check
or money order, along with a "core" manifold. (if needed)
Orders take 2 to 4 weeks to fill. PayPal can be used if you have cash
balance in the account. Credit card funded PayPal must add 3% to total
sent.

You may already have this link to the web page showing photos of the
manifolds:

Good luck on getting the car Mikey. I think that if anyone here deserves it you do!!!!
