hello there fellas! I have a 2004, and i have been researching camshafts on this forum with the aid of the search function. However i do have two questions, i'd like a direct answers to.

1) i have settled on a mild cam the GT2-3 from Lingenfelter, and i was wondering if the computer has to be messed with after install.

2) I did read the "Add 100 HP to Gen III Small-Blocks" on Car Craft, and was surprised to read that when installing a cam on the Gen III that you can just spin the engine over two revolutions the lifters will sit up out of the way so you dont have to pull the intake on the engine. I found a post that confirms this, but it mentioned using a dowel rod for safety's sake, but did not give a recommended size.

also i am open to suggestions on the cam and install, its my first time researching a cam replacement, so any and all suggestions are great. I have learned allot by just reading about it on the other posts, but any advice is great even when repeated.
