349 CI on the cheap
To lower the compression a little more for street use,how about this piston?

Comp height is 1.658. With an .028 head gasket and a 75 cc chamber, compression comes out at 9.73:1. This piston would be .001 above with cutting the deck .030. Find the right head gasket and you have your quench! This piston is a flat top truck piston. No valve notches so lift will be limited,but I bet it will make for a great 400 ft/lb + of torque plus it's light weight being cast. Best of all,it's cheap!
