Are A bodies more popular than B bodies?
It is sorta like the "any car made after '71 is NOT a real muscle car. No matter what brand and thus worth squat. I disagree, as to most any car restored will have the engine built to suit the builder. Sure the "real" sought after model will be worth more $ than the built wanna be. Well maybe the restomod prices will change that somewhat too.
IMO the rear end gear has so much to do with the eat of the pants feel of torque. Put a 3:55 or 3:91 in any car A,B, or E and the fun factor climbs pretty fast!
I agree that the size and even weight of the A makes them very appealing in this age of the small-ish car.
