Sasquatch, I wish my Conv did that. It accelerates when I punch it, but not nearly what it did when it kicked down. I wonder if your car enjoys something exclusive to hearses. I thought the vacuum to the tranny was associated with upshift points and not downshifting. I was hoping to connect my stock kick-down backwards behind the carb somewhere. Let's see who else weighs in on this, although this thread is now off-topic. I just don't want to start another Q-Jet v. Eddy war going.
I've read those posts. That debate is like manifold v. ported vacuum to advance, abortion, the death penalty, and Iraq: Nobody is going to change their minds.
