66 Dart Help Needed

Seems like you're going to a lot of trouble to build a car that will only race 2-3 X /yr. Haven't heard of a 270 Touring. What body style and trim is it?

Now that I'm done carping, I may have a few suggestions that may be helpful. RE: Axles. I'm piecing together an 8.75 rear. I had a set of Moser shafts made up with the BBP for the A-body housing for little more than cutting down a pair of B-body shafts. RE: Gears. You're not likely to find 4:30s in a salvage yard, even in a truck. Suggest putting a want ad in on FABO, and check with racers who are leaving the 8.75 for a Dana 60. 4.30:1 is a ratio that is usually the province of racers, expect to find gears that have been hammered badly.

You can grab upper control arms and spindles from a 73+ for BBP disk brakes on your 66. While you're at it, get the master cylinder and distribution block from a 73-76 disk brake A-body as well. The newer assemblies will widen your front track out by about an inch and a half. This could make for some tight clearance on the outside view surface of the tire.

You can also use the 73-74 E-body spindle and brake as well. Some here will say that the 68-71 B-body and the F/M/J spindle will work, too. They will fit, but are not recommended.

If you decide to use a non-A-body spindle, the UCA must come from a 73+ A-body. The UCA does not need to come from a disk brake car as they all had the larger ball joint.

The engine selection seems to be a no brainer. More cubes is better. Caveat Emptor. It may be advisable to seek out the specifications of the camshaft. While the cam may be happy with the 4.30:1 rear, is it going to be happy the other 49-50 weeks of the year you aren't racing? For the recommendations I've seen other FABO members make, I can't recall one going over .520 lift. Most have stopped at .505 for the street.

There is a Mopar OD that doesn't require the computer. I can't remember which model it is.

While the exterior trim is usually make and model specific on the 66s, the same can not be said for a lot of the interior trim. I've found glove box doors and door hardware on other cars. The plastic trim on the front doors that says "Dart 270" can be found on a 65 model car. On the exterior trim, the chrome strips on the rear fender tops and the pot metal trim on the tail lights inter changes with the 65 model. I found that the driver's side is the hardest to find unblemished by the ravages of leaded fuel and no pollution control.

Back in the day, Doug's Headers made a good set for the '66 A-body. Dual exhausts are problematic for the 66 and earlier models. The TB cross-member is only notched for an exhaust pipe on the driver's side. ALL that I have seen that have routed the PAX side exhaust under the cross-member have crushed the pipe at some time. Suggest the Doug's tied to a 273-4v type exhaust. The sound of those oldies was beautiful.
