ive searched..and i cant find what im looking for...I plan on doing a CC306 cam instal and I have a few questions..
-with the comp 987's do i need to machine the heads?(i plan on doing these in my garage but i dont want to have to mess with the heads like that)
-would i need shims and how would i know
-why NSA instead of SA
-i know this is asked a milllllion times but can someone give me a part#/price/ list for the 306 set up.(i want to go with 987's and steel retainers) thank you for your help and time.

 

i was also looking at the beehive springs..seems people like those better and they require less work..any info on these? and 10* or 7* locks? lol(alot of questions here)

 

Yes the spring pockets need machined for the double springs. I wouldn't suggest hacking at them your self. I used the beehive when I put the 306 in my car. You have to buy new retainers so you can choose to use stock locks or not. I didn't want to pull the heads for machining so thats the route I took. Seems to work alright by the #'s in my sig.

 

yeah..thats more than enough for me. thanks. I just picked up the 306 today now i just need to find some behives. what else did you use when you installed it? (timing chain, rockers, pushrods ect)?

 

Not sure on your other mods but definately headers and catback to let that baby breath. To go with the cam install you'll need hardened push rods, guide plates, NSA rockers, gaskets, and I went with the LT4 Extreme duty timing chain set to keep the waterpump stock, computer tune, spark plugs, I went with the over the valvecover wires to keep from burning them off on the headers. It'll set you back some cash but it'll put a big smile on your face everytime you winder up past 3000 rpm.

 

heh yeah..is it possible to use a new stock chain? im not looking to turn past 6k. might add a 100shot.

 

I'm sure the stock chain would safice but my project isn't stopping at cam only. The stock heads hp peaks at 6000 anyhow.

 

If you aren't going to turn past 6k, don't get the cc306.

 

already got it. its peak is 5800 rpms(according to specs)

 

i never understood that either..the cam specs. from what i've read and heard the 306 revs much higher then that. my cam start pulling real good at the higher rpm's and its not as big as the 306
