My '71 Newport

Yes, I believe the same feel would occur around town at least with the same high stall converter used in the 383-4 bbl cars from the factory without the 4 bbl, as in the case of most 360s too. On the highway, the 4 bbl would feel better and less constrained in airflow in either case.

One difference is also that the 383-4 bbl cars use the 3.23 rear axle ratio instead of the 2.76 on the 383-2 bbl. cars, but I don't think that buys all that much in feel since the 360-2 bbl cars generally come with 2.76s and still feel very good. The purpose of the higher stall converter on the 383-4 bbl cars is to get the engine RPMs up into a higher range on launch where the pulling torque of the 383s starts to wake up compared to the lower rev ranges. 360s already have pretty good torque down low because of their relatively long stroke, but still are aided with the higher stall converter.

The obvious penalty of a high stall converter is fuel consumption, but since our vehicles are primarily for enjoyment, few are concerned about that unless you drive your vehicle quite a bit or fuel prices are very high where you live.

To be clear, all my cars I referenced had 323s

The "low stall" and "high stall" 10.75" converters usually have a stick-on label denoting what the converter is.

I love how clean yours is. Looks like I have some competition. I have a thing for GA4 Mopars. Here’s my 1971 Polara, also a 383 2bbl that I am attempting to restore, but I will be going a 4bbl performance route. If you have a Facebook, look up GA4 Light Gunmetal Metallic/Winchester Grey Mopars. Small group I made dedicated to this color. Yours is the first non-Dodge C body I’ve seen in this color

Thanks Walter. Will check that out. I love the color too. Have seen a few '71 Roadrunners and Chargers in Gunmetal. It's a cool color. I don't have facebook but my wife lets me pose as her sometimes.
On another note, my youngest son is named Walter. He's a high school Junior. Not many Walters in his generation.

I’m one of few Walters my age, and the only one in my class (junior in college). I was named after my great grandfather. My Polara was owned by my great grandmother, and on the battery warranty card I found in the glovebox, it was filled out as such.
