Hmm- I thought the LQ9 cams were 196* 196* int ext. Could be cool if they ext was the 201* as illustrated here, I might have to do a cam change just for kicks..........

It makes 300 ft lbs or more from 2000 to 5750 rpms. Just thought some people would like to know this.

Ok...after looking over the page again....it says at the top, Hot Cam in the right place but in the cam specs is the 196*/201*. So, I don't know why they would list Hot Cam up top and not be the right specs.

I saw this in the latest GM High-Tech magazine. It's a long block 5.3L HO. Instead of the L33 (aluminum) it's cast iron. What brings it from stock 295 hp to 332 hp is the GMPP cam 196/201 .467/.479 and Grafal-coated hypereutectic pistons.
