I can get a hold of a LQ9 (6.0L) camshaft for cheap under $100. This cam is basically what makes the difference between GM's Performance parts new 5.3 HO engine and the stock 5.3. I want to install that cam in my 5.3 Avalanche. The LQ9 cam specs out at . 467/. 479 and 196/201. The stock cam is . 457/. 466 and 191/190. I know its not that much diffrence but that cam in the 5.3 HO engine makes 332 hp and 352 lb-ft. Thats 37hp & 27 lb-ft over stock. I know that with that they also put special coated pistons with that but I figure this cam swap has to be worth aleast 20hp.

Anything I should look out for? or opinions?
