440 compression boost

What are your plans for the engine? Will it be an everyday street driver? If so, no need for close to 10:1. YOU HAVE 440 cubes at your disposal. It's gonna have pavement peeling torque regardless, as long as you build for the compression ratio you use. You'll be sorry sitting in traffic in the summer with heat soak when all it can do is spark knock and rattle. There are other ways to make one haul *** besides compression. Keep in mind the general rule of thumb is for every 1 compression point raised, your return is only about 3% all else equal. If it's a street only car, my recommendation is to work with the stock compression ratio and build the rest of the engine to match.
