Definitely, degreeing the cam is the only proper way to install a cam. It is time consuming but necessary. Cam degreeing is necessary to check the cams position in relation to the crank, just a few degrees off and it can make a big difference on how the engine runs. Check out comp cams,they have a degree wheel kit that will work with the engine in the car

Agreed, do it right and make sure the valve events are where intended. The quality control at the cam companies is human (AKA: mistakes happen), and even when inside their specs/limits can be several degrees off. THEN, you also have to consider the differences from one timing set to another and how far they can be off.

Correct: To adjust the VE's you must have an adjustable timing set.

the dot there is intended to be the as ground setting. BUT, when they machine the cam, crank, timing chain, sometimes they can be off a tiny bit can equal a noticible diff. of the exact spec the cam in installed at. the stock timing chain is not adj.. older eng.'s you could drill out the 3 cam/timing bolt holes, install offset keys, and move the gear around on the end of the cam to get what you want. just google cam degree adn Im sure tons of article's are out there that explain the theory and practice. when I did mine, I found tons of pics online and articles. its ont that hard, but it'll cost a couple hundred bucks to buy the stuff and some time to do it. you'll need the small diam. wheel to do it in the car.

yes. but it would still run. not off as much as one tooth would be. it would still run fine. just not goin to get what the cam is supposed to give you if its not installed on the right intake center line (ICL). you cant change the LSA, but you can change the ICL with the adj. timing chain. for the most part, you'll just want to make sure its perfectly straight up as designed IN YOUR ENGINE. but if you were to be doin testing on a dyno you could advance or retard the cam timing (ICL) to move the power band around.

Definitely should degree the cam. Last 2 cams i've purchased were both 6 degrees off. Sadly my keyways were @ -4, 0, and +4. Would've been ideal to have at +6, but better than @ 0 without degreeing it to check.
I scratched my head a couple times the first time i did it, but once you see what's going on it's easy, and kinda fun. Or i could just be easily ammused..
