I am also new to this forum so hopefully I am doing this right. I purchased an all aluminum 5.3L (L33) engine with 180,000 miles from local salvage yard with computer and wiring for $600. I presently have it at machine shop getting it cleaned and bored +.10 ($250), will install new piston and rings ($350). Hoping to install a stock LS6 intake, if I can find one, and a stock LS6 cam. The question I have is the LS6 cam, I have been browsing through some threads and sounds like that might be the wrong cam for this engine. Since the L33 has flat top pistons I might have piston to valve clearance problems, also others indicate no power increase until after 5500 rpm. I would like to use a stock cam preferable an LS6 but would be open to other GM stock cams. Has anyone installed a LS6 cam in an L33 and had good results. Not looking for rough idling engine but, I would like to add about 30-40 hp to this engine if possible. Maybe the LS6 is not the answer. As a fall back I could go with a special ground cam from a cam company. Any words of advise??

granted i have a 5.7 but my ls6 cam is pretty mild. make a few phone calls but i'd be looking at a 220 or 224 cam. just my one cent. if you had a 5.7 i'd tell you to look at a 228.

I see your trying to squeeze a little more power out of the motor without making it idle so crazy I take it you dont like the chop chop chop sound like I do lol, so if I may say so talk to your engine builder and see if he can spec you out a cam in the neighborhood of 224/224 580/580 114 lsa the lobe separation angle is where you get that choppy idle that you dont like so instead of running a 110lsa that would be super chopy gi to even a 115 lsa I think you'll be happy good luck

For your hp goal, I too would look into getting a custom cam spec'd out for you that will make more power than the LS6 cam while still maintaining a mild idle.

The ls6 cam is ok but better cams are out there. Our High Lift Hot Cam would prob be what you ar looking for. Its designed work with smaller cid engines also and is fun to drive ans sounds goo also.
$515 for cam and springs.

On your other questions you wont have any ptv issues with th ls6 cam and its more designed for higher rpm use.
