OK, as promised here are the cam specifications (see attached image). Note, the cam lobes are Comp 3340R (Intake) and 3341R (Exhaust). These lobes are set up for a Chevrolet Big Block engine, but were ground on an LS1 Cam Blank. If you went to about a 111 degree lobe center line (versus my 109) your idle quality would be silky smooth where mine has a hint of surging and your emissions would be a little better. However, you would loose a little low to mid-range torque and you might extend the power band upward two or three hundred RPM's.
You could reuse all of your stock components except I would change to the Comp 26915 Valve Springs and the 774 Spring Retainers and I would go to the 7955 Push Rods (they are slightly longer than stock to compensate for the smaller base circle on the cam and a lot stiffer than factory).
All my best,
Steve

Hi,
Thanks for the info!
Would it be worth the expense to install LT headers, for my purpouse?
I have seen claims of 20-25 Hp/Tq for the LTīs.
I have searched to no avail for a dynochart on LTīs on a stock 5.3,
any oune know wher to find one?
