Some of the old big blocks are no-go types, but let me share a little story that initiated me well:
Second time down the 1320 and what do I line up against? An old POS looking (key word here --> "looking") Nova with about four quarts of bondo on half of the body panels, a primer gray door, silver hood and gold painted trunk. Anyways, the car sounds like it was about to stall off the line and at the time I didn't really know what sounded "mean" and what sounded like a tired old carbed V8 that hadn't had a tune up since I was born back in 1975. So we line them up and the tree falls and guess what? This POS Nova is at the 330' mark by the time I get my Stang out of 1st gear! This thing hauled balls!

I was so scared from the sound it made when it launched that I didn't know what to do. Anyways, he runs a mid 11 and I run a solid 14.7 something or other (stock everything back then).
So, I do respect the "older" muscle cars, but come on, he had nearly 100 cubes on me!

I guess the roll cage should have clued me in.
