I have the cc306 with ported edelbrock heads that flow around the same as AI's Trickflow 215cc heads. The car ran a 12.1 with my old opti (have since upgraded). I have been running the cc306 cam ever since I upgraded my heads; I had a LPE 211/219 cam that I ran when I was cam only. Do you think the LPE cam would make more power or should I move to AI's 230/238 cam? The motor is 355; I am just not impressed with the cc306.

Were are you shifting? A4? What size stall? Ever had the car on a dyno?

I'd say everything else is holding you back.

I've seen people hit 11's w/ the 306...

what else do you have?

People can hit 10s with a 306 size cam

You should post the entire time slip so we can see whats going on...At least what was your mph and 60' time...Too many variables left unknown to give you a good answer...

You did the 306 and heads at the same time??

If so why the assumption it is the cam?

IMO both choices were poor ones. If you like AI's results why not buy their product rather than have someone PRETEND to duplicate it? Lots of shops make lots of claims, doesn't make it true, and any reputable shop will tell you flow numbers are not that big a deal, they are just something customers fixate on because it is a simple thing to compare, does not mean it is meaningful.

The car is a m6 with 4.11 gears, borla catback, pacesetter longtubes, msd opti, 10 mm plug wires, crane 1.6 rockers (gold).

I have had both cams in the car and the cc306 went in before the heads. The LPE cam was the first cam the car had and it dropped my 1/4 mile time by .6 of a second.

The only things that i can really say the car doesn't have are a dyno tune and an upgraded intake manifold. My buddy tuned it on his laptop (and no he isn't a dumb***).

60': 1.885
R/T: .278
1/8 Mile ET: 7.847
1/8 Mile MPH: 90.99
1/4 Mile ET: 12.126
1/4 Mile MPH: 110.76

Your mph seems real low, I was trapping higher cam only thru an auto. Where are you shifting the car that seems to maybe be an issue? The cc306 will definetly make more power and outrun the same setup car with that LPE cam but ONLY if you are shifting it where it wants to be. If your undershifting your setup no matter what heads or cam you have it will never run the optimal times that it could. Im assuming your shifting low here and if you are and you change that Im sure you will see better results aka 11's!

Are you running a stock shortblock? If you are then I can understand why you might now want to spin it up to the 6800(ish) rpm that cam likes to see. If youve got a built shortblock in her, and she can handle the rpm's, let her have it. I bet it'll pull like a freight train.

You could do it on the stock shortblock too, but it'll only be a matter of time before it grenades :-(

I am shifting the car at 6800 exactly (using a shift light). The only thing I can think of is the car hasn't been dyno tuned. I am not sure how much a dyno tune would improve my times or horsepower but I guess I should give that a shot. I even thought about getting a hogan intake manifold.

The stock intake is not holding you back.

Go through your ignition and make sure its all good, just double check

My freinds can also tune good, but there not tuners so keep that in mind....


And 1.8 "60" isnt exactly good, try and get it into the 1.6s at least

94Z28man

I understand that my intake isn't necessarily holding me back but an upgraded intake definately wouldn't hurt. And yeah, the tune is the only thing that I can think of that would be keeping me from better times. I will go over my ignition again; I'm beginning to wonder if the flow numbers for the heads were inflated because something just doesnt seem right. I may pull them off and have them flow tested at someplace other than the porter.

Thanks guys for all your responses.

Yea, your porter is probably blowing smoke up your rear, AI Trick Flow 215 numbers arent easy to get. Plus your trapping about 3-5mph slower than cars with stock heads, same cam, and about the same bolt on's. I'd get the tune done by a professional, no offense to your friend but they dont always know everything it takes. Were you tuned correctly for bigger injectors? Is your fuel pump keeping up? What tires are you running, aka are you geared right for the tires height? Lot's of things make cars quick, it's not just about throwing money at them.

I don't think the cc306 is holding you back. I made 415rwhp with old MTI ported stock heads and a CC 306. Ran 11.4 @ 120mph with a stock shortblock on motor @ 3400 pounds. Did you tune it with a wideband on the road?

No, Chris I didnt tune it with a wideband. I believe that tuning is one of my major issues. The heads on the car are ported edelbrock heads; I am now wondering if I can send them to AI and have them reported.

I would suggest getting it dyno tuned first.

94Z28man

iTrader: (1)

I want to get it dyno tuned but I am beginning to doubt that the heads actually flow good at all.

LM97Z

iTrader: (4)

I'm sure the heads are fine, eddy heads are good heads, they may not flow exactly as claimed, but they do make decent power, i would listen to what was said about getting it tuned 1st. before ripping the engine back down, because if that cam works well with stock heads, its only going to work better with aftermarkets, thats my thoughts anyhow. You may have other issues holding you back.

Get her on a dyno and see what they can do for you. When I put together the 383 that was in my car I was running a cc306. First pull on a dyno was 385ish whp. After the tune it made 423whp. That could be your difference right there.
