B vs RB

I couldn't have said it better.

Hey I'm old. I saw these cars race when new. When a well set up 340 showed up,it was
over. You didn't have to spend a bunch to get a 340 dart to stick, but 383-440 B blocks needed tires, and skill to drive. any Amatuer could step on a 340 Dart and go fast. That is how it was. I have a 383 Cuda, and this doesn't take anything away from them, but a 340 A body was like riding a Z1-A 900 Kawasaki in1974. Docile and subservient
, until you cranked it. That was one bad bike. Sorry for the History lesson.
