383 Stroker build

Hey everybody, I'm hoping for some people much more experienced than myself to evaluate this build! This is what a local engine builder has come up with for me. I have asked for a 500 to 600hp 383 stroker build. Probably not relevant as to the build itself but it's going in a 67 Dart with a Torqueflite, 3.55 gears and 28in tires. Torque converter will be built/bought to match the engine and transmission build.
Will be expected to run on 92 pump gas
