1966 Dart D-Dart cam spec

That Isky cam will make ur 273 so sad that it will make u want to cry if u even think of taking ur car for a drive. Contact 4spdragtop, he had the Comp 270 in a 273, I believe he has taken it out. He can give u some insight. I love the choppy sound even now but I have the reduced drive ability of a tiny engine with a big cam. Kim

You've been given MANY good recommendations and you keep asking for more.

Rusty, that’s because we haven’t told him what he wants to hear. Yet another thread where the op asks for advice but literally ignores everyones posts. Kim

It certainly appears that way, doesn't it?

I appreciate everyone's input, I am just trying to find a cam that will perform and have some kind of sound profile, I don't plan on driving the car much outside of town, it is just a street machine and if I want to go fast, I have other cars that will serve that purpose. I just want my Dart to sound good and perform better than it does. That little E-2 I have is just terrible, sounds like a sewing machine and I just can't live with that. If anyone has a good recommendation on what cam to get, I would appreciate or otherwise I am gonna buy this cam: SB Chrysler Performance Flat Tappet Cam & Lifter Kit - 286°/294°, 242°/246°@ | USA Performance Parts

Have Isky grind that custom one, or have my buddy Don Johansen grind me a true D-Dart cam.

On the rear end gears, I know a 3.91 is gonna be steep with the 3.09 first gear in the 4 speed, but they were affordable and are for the 741 case in my early B-Body rear end in my Dart.

here are the specs on the cam I had in my first 273 with the low compression pistons ........ pretty much the same cam , different number though >>> 1m286y advertised duration 286* - 510 lift . similar specs to the D-dart 273

Yes Kim ........ that cam won't come alive until 4k and still won't have any power....it will be a "pooch" for sure !

Now...... this d-dart has a serious 273 commando in it . it means business not like the golden commando 65 barracuda . this 66 d-dart is one healthy sb. you can hear the difference in sound of the two cars.

This one has a 340 in it. The original engine was trashed back in 66. Tracey actually raced the car this past weekend with a new engine in it.

Thanks TMM. Hope this works.
This is my D/Dart. The first one built. I believe it currently has the Racer Brown SR-21 cam in it.

Ted Spehar experimented with the ST-12 cam
ST-12

As released the D/Dart cam was PN - 2843919

Sorry about the rough idle. Needs new plugs. It is a healthy engine though. Original block, intake, carb ....
