Just rambling....

A 470/500" low deck, built like your talking about would be awesome in my book. Big torque and decent drivability would scream in a "A" body. Thinking back to the late 60's/early 70's......ie. long stroke, Buick, Olds, Pont, 455's.....with a decent tune, and bolt on's, would pull some fairly heavy cars into the 12's. No reason why A,B, or even a C body can't run extremely strong with a 500lb torque curve between 3000/4000 rpm's. A ton of guys bracket raced combo's like that years ago, shifting between 5000/5500, and the engines lived for 2,3 or more seasons without a freshening.
