degreeing a cam I'm getting ready to install heads and cam on my 02 z28. My cam is 238/244 .605./610 lsa 110 +2 the card says to install it on a 108 icl. I have read through the instructions on how to degree it, and I am going to be doing the install with someone that has done it before, but wanted some input from you guys.
-What kind of degreeing kit do i need, just the one from comp, anything special with it i need to get?
-I did buy the ls2 timing chain but i was going to use the stock sprockets, but because i need to degree the cam, i guessing i should get a adj. sprocket?
-Any inputs on degreeing? Tricks learned?
Thanks for any input

One of the best tools is the LS1 tool that holds the timing wheel and goes over the oil pump sprocket. This is used for turning the motor and adjusting the wheel. Their degree kit is pretty nice too. I got the heads on kit since it includes a lot more stuff and then just picked up an extension for the dial indicator since I am doing it heads off.

Who makes it?

Yep, you will need a timing set like the Hex-adjust. You can set it up with the ICL method, but JPH is telling you to check the Intake Valve Open and Close degrees. The cam card will list those valve events. You turn the engine clockwise til the intake valve opens at .050" and record the reading on the degree wheel. Then continue to rotate same direction until the valve is .050" before it seats and record that number. Don't be suprised if it is a degree or so off. Just adjust the cam sprocket to dial it in.
The ICL method has you check at .050" before and after max lift. Add the the two readings and divide by two. If the lobe is not symmetrical it will throw off the readings. Always turn the engine clockwise, dont go backwards like some will tell you with this method.
Also, either of these processes are only good if you find exact TDC before you start.

Its not cheap but worth its weight in gold. Its one of those high quality tools you will be glad to have. It mates right up to the Comp Cams degree kit as well. I plan to use it for degreeing the cam as well as measuring PTV using the dial indicator since you will be able to leave it right in place once the cam is done and install the head and go from there.
