Hi Dave,
we are all different with different opinions. That is good !
I have a 71 SF with 383-2. Also had a 69 Mod Top Satellite with 383-2. Combined with 2,76 gears it has a lack of torque IMHO. They also have converters with lower stall than the 383-4 engines.
All my wagons with 383s felt slow. They were 383-4 cars (70 Sport Suburban, 69&70 T&C).
Surprisingly my 72 Sport Suburban with a 360 felt and drove faster than most of my 383 wagons.
Despite my C-bodys I am used to drive B-Body Muscle cars (all 4-speeds), most of them with 4,10/3,54 or 3,91 gears. I like the "kick in" of plenty of torque.
I am missing that power in a C-body due to several reasons.
Unfortunatly no 4-speed fuselage C-Bodys were built, second the gears are longer (3,23 is the shortest gear).
So for a "quick pass" in heavy traffic you need to accelerate fast.
Or if you have to rush to turn over an intersection.
