My new 340 at the track

I have a very nice stock crank 360 shortblock I built a couple of years ago that I built for my son to get back out. I bought everything from a Moparts member. He joined here shortly after but I Dont know if he comes on here anymore. Originally I bought the Crower rods, stock 360 crank cut down to Chevy size, very nice oil pan he built, pistons, etc then he offered me the bushed block so
I made another road trip. It included a nice .660 lift roller cam and used Crower lifters. I’m sure it would be the 9’s somewhere with my Edelbrock heads but the crank being cut to Chevy size kinda scares me. Curiosity may force me to try it someday.
