I remember being in the staging lanes at the track one time and there was a guy chatting with the owner of this 69 a12 4 speed car that was running high tens.
I don’t recall what the question was, but the answer was, “I’ve broken everything you can break from the block rearward......and a few things more than once”.

That’s the thought that comes to mind when I think: heavy car, 833, nitrous.
