So as I understand Aussie street speed has took over production of dultra duals. Is it still possible to get dultra duals from Doug. And do the Aussie duals have compatabilty for an automatic choke and heat provisions.

You'd have to ask him... Doctor Dodge

To my knowledge, the only manifolds with the choke provision are factory units. Retaining the rear half of the factory manifold would allow you to use the factory cast choke provision.

I am sold out of Dutra Dual castings so contact Aussie Speed for price and availability.
The Dutra manifold never had choke mounting provisions so no choke, a manual choke or welding-on the mounting provision are your options.

the Aussie Speed version of the Dutra's claim to have fixed many of the mounting issues
that the original Dutra's had. I am not complaining about what Doc offered, I have had a set on my
83 D150 for several years now and they have held up fine. They are a good value.
But I did need to grind the blocks transfer lugs and the rear manifold to add clearance over the
starter, and Aussie Speed say they have fixed that, so that is a good thing.
