Don't think he was getting anything off his chest. Your asking about a 228 cam in a 5.3 that will need a decent stall. Both of which cost $$$ just like gas. Both of which will hurt gas mileage. Do your research, some one asks the same question every week. I'm not tryin to bust your balls but read up. Learn about what you have, need, and want. Then figure out how it goes together.
Ask questions to increase your knowledge, not to solve your problems.
