Question about 340 vs. 440 (From newbie)

Murray said
...If you are considering a mid-sized car like a Roadrunner, these are referred to as "B"bodies and include Roadrunner, GTX and Satilite. These cars could come with slant 6, V8's from 318 to 360, with some rarer ones having 383, 440, 426...

Just to clarify: All '68-'71 Road Runners came with a big block, 383s at a minimum. Minimum engine in as GTX was a 440. Later on they got small blocks.
