I'm sure this is a question for the ages that pops up a lot but I have to ask.

My car is in my sig and it is basically stock. I want a fairly decent power increases so I'm looking into running a comp cam with stock heads and stock intake. Mod's that will be done is full exhaust, intake, maf, and air foil. Those are just the definates. Here is where it gets confusing to me.

I was looking into doing a CC306 and 1.6 RR's. If I do this I'm assuming I can't run my stock computer and I'll need a tune right? What kind of power numbers do you think I'll put done to the rear wheels with a combo like that?

If you guys can recommend any other combo's please let me know, I'm very open to idea's. I'm just exploring my options right now because I'd like to get this project done this winter while my car is hibernating.

Any advice is much appreciated.

Thanks in advance.

by the way the car is daily driver

 

If you go with that cam, you will definately need to get the car tuned. There are a few really good mail order tuners available if you don't have the money to get your car dyno tuned. I recommend PCMforless.

The power you put down will vary, but with a good tune and if your car is pretty strong running, I would expect anywhere from 350-370 RWHP from that setup.

If you want to go a little bigger you could look into getting the GM847 cam. There is a guy on here putting down around 380 RWHP with that cam and boltons through an M6.

 

350-370 was my guess also... stock heads will be your clog. open them up or get some aftermarket's and you could see over 400

 

thanks for the replies guys.

I plan on taking the heads and intake manifold off and getting them ported eventually. For now I just want to figure out a good cam and get it in there.

I've heard with this cam (CC306) you need to run high gears, I'm assuming my 3.42's ain't high enough so I was looking into possibly 3.90's or 4.10's.

Also I geuss new springs and rocker arms are necessary too?

Also any idea on how much a cam install costs about? Still debating on whether or not I want to tackle this task myself or not.

 

Replacing the springs is going to be a MUST. The stock springs won't handle that much lift without binding. I recommend Crane Double Springs,(Crane Part number 99893-16).

As far as gears, since you are running an M6, you should go with some 4.10s. They are still very streetable with those two overdrive gears.

 

i'd be happy with 380...cc306 goes in next week...car already has gtp stage 2 heads and matched intake

 

so as its looking right now with doing the cam.

I'll need to do rocker arms, springs, and tune.

96 and 97 didn't have harden pushrods right? I'm I going to run into a problem with that?

Also am I setting myself up for a fall by doing this? My car has 78K on it and it is a daily driver that I need to last. Will my engine take a dump on me by doing this?

 

Yes you will also need to get some hardened pushrods. 78K is not that many miles IMHO and several people have put cams in their LT1s with well over 100K and had no problems

 

This swap is adding up really fast.

So with the cam, rocker arms, springs, push rods, a tune, and gears I'm looking at circa $900 in parts and then whatever the install costs.

And after all that there is a chance that I'll throw a cam bearing...

It's something I really have to think about before I go through with this.

 

what size valves?? 2fast made close to 400hp with a 847 (similar to 306) 4000 stall and stock casting heads with 2.02 intake 1.60 exhaust I belive. you could make close or more with better heads

 

2.00/1.56 valves

 

im also putting in a cc306 next week and this is my parts list

CC306
kmotion k800 dual valve springs
comp valve spring locators
comp 10* valve locks
comp titanium retainers
GM guideplates
comp hardened pushrods
comp pro magnum nsa 1.6 roller rockers
new timing chain
comp 7/16 rocker studs
comp lifters
gasket set

 

I can't remember the guy's handle. He put down 377 RWHP with the stock untouched heads.

 

2Fast4Lv (Ellis) I thought made closer to 390 with LE (Stage 2)? heads and the 847. Impressive with a a4 big stall and 12 bolt And went 11.80's at 110+(if memory serves me correctly)

 

any opinions on the CC305?

My car is a daily driven street car, do you think I'd be better off with reliablity and gas mileage wise with a CC305?

How big of a power difference is there?

 

dsmawd350 if you don't mind me asking what is the swap running you parts wise and installion wise?

 

cc305 is very streetable...but power seems to die out a 5500 at most, so hopefully with the cc306 power will go to 6200+ (will have shift points moved to 6500)

 

ill go ahead and post up the prices i picked up these parts for but some i got used.

cc306- $150 used with 6k miles on it

k-motion k800s- 89.95 from summit

comp valve spring locators- 39.99 from summit

comp valve locks- 24.88 from summit

comp titanium retainers- 100 brand new but from a guy that didnt end up using them, but they run 130 from summit

GM guideplates- 26.00 from thunder racing

comp hardened pushrods- 35.95 from thunder racing

comp pro magnum nsa 1.6 roller rockers- 260.00 from summit

oem replacement timing chain- 35.00 from combination motorsports

comp 7/16 rocker studs- 31.00 from combination motorsports

comp lifters- 200.00 from combination motorsports

gasket set- 38.00 from combination motorsports


so ill have about 1000 dollars in parts and i was quoted 500 for install and 250 for a tune

 

I'd love to go witht he CC306 but since my car is a daily driver as does take ocassionally road trips I think I may go with the CC305.

Anyone know what kind of power I should put down with the CC305 and stock heads and intake, bolt-ons and a tune?

Thanks again for all the input everyone, this is really helping me out.
