carbureted 5.7 - 6.1

You have to be carefull and make wise decisions on choices. 11-1 with stock pistons and 5.7L heads , I dont think so. You also have to be carefull with cam selection and stock pistons. There is no doubt in my mind than more than 450hp is attainable with a stock bottom, mabe some head work, and a camshaft that will fit without valve notches.
