hey guys. bought a cc503, have my headers on and my new flowmaster true duals. anyway i saw this article about a guy bending all his push rods with his 306 cam install. so before i go ahead about stickin this cam in along with my 1.6'' rockers, is there ANY other info i need so i wont F up and cost myself money i DONT have. thank you .

 

i recently installed a cc503, what exactly are you needing to know? and BTW something will come up and you will be spending money. thats just the way it works. done all of that and i still had to go back and replace my opti and wires. BLAH. just pay extra attention to your rocker arm adjustment once you get the cam in. as far as cam install just get specific with what you need to know and ill help.

 

alright. well how do i adjust my rocker arms correctly and KNOW they are correct. also can i keep my stock LT springs???? that's probably really all i need to know. BTW i just replaced my opti and plugs last summer so that's a relief lol. the car was overheatin due to my impellers in my water pump...they were well, disintegrated lol. replaced the pump but it was too late. the H.Gasket was blown already. im getting my heads decked tomorrow because the passenger side is badly warped. nothin a machine can't fix though . so, had to tear engine apart and figured might as well throw a nice cam and 1.6'' rockers in it so i can keep up with those p.o.s. fords. thanks green

 

You can find cam install and valve adjustment instructions on my Tech Page. And no, you don't want to keep your existing valve springs. That would be the serious mistake you want to avoid.

 

hey shoe, any idea on which set of springs to go with. and also a nice set of rockers. i know the cam is from comp cams i want, but i dont really want to spend more that 250 on the R.R.'s and well i dont know how much springs roll for....

 

Folks here tend to opt for the PAC springs, through I don't know the spring rate for the CC503 Cam. Definitely upgrade the springs. The search here is pretty good.

 

Lloyd Elliott has had some posts with spring recommendations. You might try a search or contact him for info.

LE posted his spring recommendations on LS1LT1.Com on the LT1 board, right at the top of the page in a STICKY.

There are several different ways to set lifter preload ("adjust my rocker arms"). All of 'em will work but only if done correctly. Here's how CompCams says to do it:

Section I. Setting preload with ADJUSTABLE ROCKER ARMS
Turn the engine in the normal direction of rotation. Start with cylinder number one (1).

When the exhaust valve begins to move, adjust the intake valve to the correct preload.

To reach zero, take the pushrod between your finger tips and move it up and down while you tighten the rocker arm.

Once you feel the pushrod has no more vertical slack, you are at zero preload.

Make sure the pushrod is in the lifter and the rocker arm seat when making valve adjustments.

As stated before the best setting is .030” to .040”, or ½ to ¾ a turn of the wrench past zero.

Now, you can move on to the exhaust valve on the same cylinder.

Begin by rotating the engine over again until the intake valve reaches maximum lift and is almost all the way back down.

Then set the exhaust valve using the same method as the intake (.030” to .040”, or ½ to ¾ a turn of the wrench past zero).

Continue adjusting the valves on each cylinder in this manner until all valves are adjusted.

If you choose to ignore this recommended method and, instead, try using the TDC method which is shown in some of the manuals, you're bound to be posting here again when that method causes you problems. Just a Word to the Wise. Your call though.

what type of rockers

 

Save yourself problems later and get a good set of NON Self Aligning rockers, hardened pushrods, and guideplates. I prefer Comp promags but some don't like the noise they make. They may be a bit loud but they won't break. The pushrods can also be had from comp but get the GMMP guideplates. The comp ones don't quite line up right on LT1's.

 

Actually there have been some recent posts where Comp Pro Magnums have broke. I run them as well and was not pleased to hear this.

 

Yep, I saw those. One broke at the trunnion and another broke at the roller tip. Still another post had SA rocker on jumping off and wedging against the side of a valve spring. Still another guy posted have one end up tearing up his spider.

All sorts of carnage going on lately.

There may have been some posts about promags breaking recently but if everyone that was running them with zero problems posted that on here there would be nothing but posts about them not breaking. How many motorheads do you think post on the boards as opposed to ones that don't? Buy whatever you want, but when your 100$ rockers break your on your own. Break a comp promag body and comp will take real good care of you.
