Hey guys I have a cleveland and will be adding a supercharger to it, so I need low compression. I have 4v closed chamber heads. What would the compression be if I added dished pistons does anyone know.

You won't be able to lower the compression enough with the closed chamber heads. This can be done with open chamber heads. You could get down as far as 8.5-1 with open chamber heads and dished pistons. Hope you have beefed up the rest of the engine before attemping this.
