I have an offenhauser single quad intake manifold that I'm putting into a '73 Dart. The car has an automatic transmission and Summit Racing mentions a special kit for automatics which must be ordered separately.

What part number is this kit and is there someplace I can get a good price on it?

I also have to replace the exhaust manifold. Should I go with a stock replacement? I don't think I have room for headers with the stuff for the power steering and automatic transmission in the way.

The engine is bored .030 and it also has a comp cams cam.

the part # you need is 5270-A. check here:

or type that # in over at summit.

if you want a replacement (new) manifold go here:

its a really nice piece and even comes with new triangle washers.

in that car there is no reason not to use Dutra Duals, even with power steering....if i am thinking right.

that seems daunting at first, but once you cut the front leg off, you can braze it together with stuff you can buy at home depot.
