gettin ready to do my first cam swap (yay) on my 2001 silverado 5.3- the engine is untouched and is a right about to roll over 100k miles. my question is what are things that can be easily replaced while have half the engine apart? here's what i have. feel free to add or take away stuff
I slide in a 212/218 low lift with zo6 springs and TSP push rods into my 5.3 at 112,000 and didn't change anything else, not even water pump gaskets. Never had a single problem with anything. I pulled the (still running) complete engine at 168,000 (with about 70 bottles put through it) when I did my 6.0, and sold it to a buddy for $600. It's now in his truck, still holds awesome oil pressure (once went 7000 miles on an oil change and only was down a 1/2 quart), not a single leak anywhere he has put 20,000 miles on it and he runs the **** out of it.
If it will make you feel better about it, do it. But seems like people always screw up cam swaps by dicking around with the oil pump. People are always pinching O rings, or what not, or causeing leaks cause the pan has to be dropped to change the oil pump and bottem sprocket. If it was mine I'd use all the stock parts, slide in the cam and be done wit it, unless your going to some radical cam with super stiff springs...
