how to re-fresh 5.7 Hemi

BTW, one thing we are seeing is a failure of the timing chain tensioners. (Just saw a 6.1 failure tonight) The tension slide on the right gives up w/ llittle notice. It's only 3 bolts to replace and it is not expensive while you are there. If you are in a motor w/ 80K or more, go ahead and do it. Some last a long long time and some are toast by 100k miles. Don't gamble w/ jumping tooth over a few bucks and a few minutes extra since you are there w/ the oil pump, anyway.

BTW, Thanks for the props to www.InertiaMotorsports.com too :) We are about to get back to the A-body projects in the next couple of weeks.

I consider that tensioner a maintenance part at 80K. It's also a good excuse to put a cam in:). the other things to look at are the springs on 03-04 trucks tend to fail. Those same year engines also have toner rings that can fail which is exacerbated by some of the underdrive pullies like the APS and Moto blue. They had a new toner ring design in late 04 that is much better. And, the pistons which you can't do anything about cheaply.
