Need a stroker test car

I can tell you by my own experience. I have a guy out the road from me that has a very big money 72 Dart with a 360 stroker. I don’t have to ride in it or drive it. To know what it runs like. His garage is under a modern brick home. He started it for me. Showing off each other’s cars. I wanted to tuck my tail between my legs and take my identical looking 360, home. When he turned the key. I thought his brick house was eventually going to be rumbled to the ground. He said, “ About 550 hp.” I didn’t doubt it one bit, lol ! I could feel the power standing next to it at idle.
