Default Anyone running a cc306 here?

Topic pretty much says it all. With a set of 4.10s I dont think it would be unstreetable by any means but would need to have some serious custom tuning to dial it in. Opinions, experiences and ideads suggested. FWIW, there are alot of F body owners running this cam on stock LT1 heads or mildly ported LT1 heads with outstanding results. Better than the hotcam.

You read my mind, I am also in the process of searching for a cam and I had the same questions about the cc306. My plan is to do the cam in the next couple of months and then send the heads out during the summer to be ported. Basically I wanted to defray the cost over some time.

Eitherway I was also wondering if the cc306 would be streetable. I want to get MAX hp out of the cam and heads without touching the bottom end at this point-- In my case the car is strictly a weekend ride so a rough idle will not be a big problem.

I am anxious to see what everyone has to say :yesnod:

cc306 specs 230 / 244, .510 / .540 112 LSA I bet this thing has one heck of a lope to it.
LT4 hotcam (with 1.6 RR) 218 / 228, .525 / .525 112 LSA

My times are in my sig. This cam made 352/340 at the rear in my Vette. This is with non-ported heads, other than the head ports being matched the intake This is a very streetable cam, and my Vette is driven daily with this cam. I will say that you need at least a 3500 stall or a stick car to get the cams full potential. I think that with some additional tuning, I should be close to 360 at the rear. :seeya

11.5 @119 with no port work and stock cid.. Not bad at all I would say.

Is this cam to big to run 1.6 rockers, do you have to stick with the 1.5's

Thanks! You can run the 1.6 rockers without a problem, I was just trying to be conservative with the lift to help the valve springs last longer due to me driving it daily. When I have my heads ported, I am going to upgrade to 1.6 rockers. :seeya

My car is an M6. With the LT4 heads (marginally better flow than stock LT1) I would hope for similar results to yours. mid 11s on stock cid and stock heads is unreal :eek:

I've been told that the 306 is a little too big for a 350ci motor. I'm very interested in this thread - ttt! :)

I have heard that also........ But apparently it's not. I will say that tuning is a key factor in making this cam work. My timing curve starts at 24deg, and finishes up at 39deg at WOT. Be sure that you get enough stall if you go with this cam. I had a 2800 in my car at first, and the car bogged out of the hole, and would 60' high 1.6's. When I upgraded from the 28 to a 3600 I am now cutting a best of 1.57 60', so you can see how much the converter helped. :seeya

Like I said in an earlier post, the only work that was done on the heads was match the head to the intake port. I have stock valves, the heads have been milled to about 11:1. GTS, you do not have to make 500 RWHP to make a car run. I will tell you that your stick car is going to be more of a challenge to run the numbers that I am due to the fact that the 6M is a hell of a lot harder on rear parts and clutches. I remember when CORKVETTE was making 340 at the rear, and he went 11.40, so why is my 352 and 11.50 hard to believe. BTW when I upgrade my heads I will sell you them.... :lol: You can do a search for DRAGRACR and see that I didn't get to where I am at overnight............

I have been told by a few people that this Cam is too big for a speed-density manual car with the stock bottom end. DRAGRACR has a automatic and maybe it is easier to tune than the manual. I would be curious to know what DRAGRACR's car idles at?

Ruby6spd - Shalin lives in Delaware and he has burned many chips for speed-density Corvettes. He now owns a Supra but I believe he still does the chip work...

I have heard that this cam is too big to pass emmsisions testing on a 350, and that you need a CC305/hotcam to get by. Is this true?
