I have ordered hundreds of things from Summit. Great parts, great prices, quick delivery.
The dyno sheet looks good. Is it a 350? Summit does sell a 383 kit. Don't know how much you have played with desktop dyno, but going to a 383 will add torque, but not horsepower. It will help the low end on a higher rpm engine.
