Lightbulb cc306 vs GM847 vs custom...

Alright, I tried the search function, but nothing really turns up about what I want to know! I have searched for a day and a half. I probably wasn't typing in the right words I guess...
Anyway, I wand to know which would be better to use, the cc306 or the GM 847 or even the lloyd elliot or AI custom cam. I have a stroker, 383, will be having lloyd do some LE2 heads or AI do their all out LT1 head. But, which cam would be better? It is a daily driver, I want more low power than top, as torque makes daily driving fun. But, HP wins the race, so I would like relatively both to a certain extent. I will be doing the pro mag NSA, what ever springs they recomend, and have 52mm ported TB, pacesetter longtubes with e-cutout, t-56 tranny, stock 3.42 rear, 42 lb injectors, ram air, egr air delete. Not sure what else you need to know. I like to cruise on the freeway in 6th gear at about 1800 rpms. Which cam would work better and why? I drive her pretty easy on the street, as when you beat on it sh*t breaks. But, I do want it fast, and a little lope at idle would be fantastic.

With the LE2 head, he says that the cam is like a cc306, but with le3 he says like GM847. I want power... and my compression will only be about 10.5:1 with these heads, so more cam might be needed...

any HELP would be appreciated, negativity can go elsewhere.
thanks everyone!

Yeah go with Lloyds heads and get a custom ground cam that will give you good lowend torque and power up to 6500 or so. The old 306 and the 847 are both great shelf cams but you could get the same kind of power and more torque from a custom grind. My 306 pulls really hard but has a little less torque then a smaller cam. Later Clint

The 383 changes the cams. A 350 LE cams are like the 306 and 847, all though the LE3 cam is recomended for a 355.

What you want out of the cam for what you use the car 95% of the time is vastly different from your power goals.

BTW if your afraid of breaking stuff, modding isin't going to help. You will break stuff then.

You should really rethink your compression, for what you want out of the motor stock compression is only going to hurt you not help you. The less compression you have the less cam you can use in a street car.

Re: cc306 vs GM847 vs custom...

I have the GM 847 in my 383 with about 10.3:1 compression , it runs like a striped butted ape (in my opinion) At the track it runs 11.7s all day long at 116 to 118 mph through a 4L60E in a full weight 97 WS-6.

BUT I think I am leaving quite a bit on the table below what an optimized cam would give me.

Re: cc306 vs GM847 vs custom...

I would also recommend bret b/c Joe is swapped right now. I don't know how fast AI is w/ cams but forgetabout getting heads done. There backed up big time go w/ Lloyd.

wssick why did you pick a low compression? supercharger?

Re: cc306 vs GM847 vs custom...

well, is there anyone who chose the the 847 and wished they went smaller, or anyone with the cc306 and wish they went bigger? Due to my stupid pistons, that compression is about all I will get. So, I have to deal with it. It will help with the use of 91 octane anyway. So, what kind of profile should I use then?
Suggestions?
thanks

Re: cc306 vs GM847 vs custom...

if your stuck w/ low compression I would go w/ one of the old lingenfelter cam's those things rock for their size.

I wouldnt think that 10.3:1 compression would be ideal for a supercharger.

Mainly because its a daily driven street car.

Re: cc306 vs GM847 vs custom...

yeah, no supercharger, just N/A. I am stuck with the 18cc dished pistons, so about 10.5 would be the highest I could get. Right now with my stock heads that is what I am at. The motor runs great, pulls strong, but now its just time for my motor to reach it's potential.
So, by having a stroker, the LE3 cam would prolly be used if I went with him?

Re: cc306 vs GM847 vs custom...

I have a little more aggresive version of a LE3 going in my 355. If your going for this size cam you want at least 12static and 8.9DCR. Compression makes the cam more streetable

Cubes also make a cam tamer.

Re: cc306 vs GM847 vs custom...

I can certainly agree with that, what was WILD for a 350/355 cid motor may be mild for a 383/396 combo, its all about having the right combo for the given setup.

Re: cc306 vs GM847 vs custom...

Firebirdstud...The 211/219 is the Lingenfelter cam I think bdc95ta is talking about. I ran this cam for almost 10 years in my LPE 383 as its the cam they used. The specs are 211/219 @ .050 and .533/.560" lift with 1.6s on a 112. This cam worked great in my 383 and everyone said that it was way too small until they saw a full weight Formula run high 11s at 115 all day long and pass MDs emissions better than any car I ever had. 24 mpg highway nice little lope. This is one of the best of the shelf small cams out there (imho)...Don't let the size fool you...

LPE also used a 219/219 which was 219/219 .050 with .560/.560 lift, but it was designed for the Superram intake...
