Anyone want to talk Chevy! LOL

Power glides can be built to hold LOTS of power. Used behind SBC on pulling tractors, with Blowers, turbos, had one behind a 1200 HP SBC. Never had issue with it. The engine was another story!
I feel comfortable with rebuilding it and or just trying it the way it is. I was just wondering for kind of a Snappy Street kind of feel is this going to make any performance effort feel kind of fruitless? Seat of the pants of course we're talking here.
