A Quick TQ I.D.

That would be the Chevy throttle arm small primary unit that 69 Cuda 440 said was rated at 737 cfm. The electric choke is a nice added on feature from Carter.

I have found the small primary TQ’s very at home on stock to very mildly modified engine of small displacements of 360 and smaller.

If anyone has a hot street engine of 330 cubes are larger, the 1.50 primary TQ will drive with a little more (& noticeable) power, a bit smoother as well. The smaller primary works well but the feel between them is apparent like the small 1.38 primary carb is struggling a little bit. The draw back to the larger primary TQ is no electric choke.

Hooking up a manual choke cable can be a tricky operation but yet possible.
