I have a 2000 rcsb with a stock 5.3. I have a set of 243's on the way that I plan on milling .030 and I am in the process of cam shopping, was wondering what off the shelf cams are safe. I know measuring is the only sure way to know but I thought I might be able to get some ideas since this is a popular head swap. I was thinking something along the lines of a tr224 or the like. Any suggestions would be greatly appreciated.
