i have a new ZZ4 in my '69. I want to install GM's Hot Cam in it with the Roller rockers. 2 questions..... Do I need to "degree" the cam in? I read about it in magazines - but I don't know how to do it (I see they say to buy a degree wheel and then they go on and on with how to do it) or if I really need to. New engine, New cam - is it really necessary? 2nd, how do you set or adjust the roller rockers? Do you set them like standard ones where you are really just preloading the lifter? Same procedure?

the rocker's will come with instruction's and so will the degree wheel tool for seting up the cam. just read them and do what they say.

i know we are men and we do not need the instructions...hehehehehehe but read and use them and you will do fine.

On another topic, what headers are you running? I have been trying to find someone else running a ZZ4 with the angle plugs.

I've got DynoMax Cerama-coat headers. from Jegs - about $220. They fit easily - a couple of the plugs are still hard to get out but not too bad.

You don't need to degree in a cam unless it is for a true race car. I have always just put it in{make sure everything clears} and if I don't like the way it runs advance or retard it to suit my needs.

The ZZ4 is perfect for the 1st gen camaros. I run a ZZ4, 700R4, 3:55, 750 holley, Hooker ceramic coated headers, which work fine with the angled plugs. I just installed the LT4 "Hot Cam", along with Comp Stamped roller tipped rockers and a pete Jackson Gear drive. It was a lot of work, mostly because everything always needs a little tweaking. This car really rocks, it gets more attention for the way it sounds (with the dual Flowmasters, etc.) than just about anything else.

Adjusting the Valves after installing the rockers is a walk in the park. The instructions tell you what to do, but the easiest way is to turn the engine over until both valves have just closed. Tighten the nut until the pushrod won't rotate with your finger, tighten 1/3 to 1/2 turn more. It's work for me for longer than I'm willing to admit.

Good luck
