I am perfectly happy not getting the full benefits from the CC306 as long as, even "short shifted" its outperforming the other off the shelf shelf cams.


Is it possible some of these myths came about because the inaccuracy of the stock tach? My tach sweeps just past 7k when in reality, it is at about 6500. The higher I rev the car, the farther the stock is off. At idle, its dead on and just gradually gets farther off as the Rs go up.

I dont take it the wrong way because you are a very nice guy too but I disagree with you. The cc306 on a stock short block with stock heads should be shifted just beyond 6500 for optimal results. That doesnt mean you couldnt shift it at 6400 or 6500 and run great times but theres still a little left. I shifted my 224/230 with the stock block and stock heads at 6400 via data master (tach was like 6800-6900!) and that was dead spot on. Any lower yielded me slower times and higher did the same as well. There are many variables no doubt but how do you figure a cam thats a 230/244 versus 224/230 would shift at the same exact rpm? The more duration the more rpm! That is the truth. If you search on this board and others you will see the best results coming from 6500+ shiftpoints with the cc306. You and I will never agree bro lol. I firmly believe Bryan set your shiftpoints there so it would still be safe on your stock bottom end. Shoot him an email and ask his reasoning and I am 99% sure he will say that.

You like to throw out names to back what you have to say and in no way am I saying they're all wrong, but someone has to be wrong in this mix. My info came straight from Bryan Herter from PCM for less. He has dyno tuned hundreds of LT1 cars with the cc306 and it's hard to believe someone with his experience would be wrong. Most of the info you got was from people that want you to buy their product instead of the off the shelf alternative. Like I said this isn't to bash you but you personally haven't used this cam and I would like to believe someone that has tuned for it several times might know something about it.

MadZ28 has said the same thing and he has tuned hundreds of LT1's. You cannot say that Advanced Induction, Bret Bauer, and Lloyd Elliot were trying to get me to buy their products when I would ask them what cams that they offer would work in a safe rpm range for a stock short block LT1. When I asked about cams similar to the size of the cc306 that they offered they told me where it should be shifted which was beyond 6500. They also offer cams the same size and larger than the cc306. However all of those cams that they recommended were noticibly smaller in duration at .050 than the cc306. They weren't selling me anything just giving their advice on how large of a cam to run. MadZ28 wasn't trying to gain any revenue when he made a thread on cz28.com in hopes of preventing people from overcamming their cars if they aren't willing to spin their motors high enough to use the cams. If these guys are telling a bunch of BS I dunno who we are to trust when we want heads, a cam, or a tune.

I actually agree with you about how this cam looks on paper. But you know just as well as I do that it's not always the truth. I don't want to keep taking up this thread anymore. I feel bad for the guy who just had a question. My opinion from what I have and use says this is a good cam if you want to go big but if you don't want to spend money on all the supporting mods go smaller. There are other choices out there. Don't run away from any of them until you have all the facts though. Good luck.

as far as shelf cams, i would say the cc306 as well because even though you get the most out of it if you can spin a little higher that 6500, you can still make some good power all the way through the powerband with stock heads. so when you do put heads on there, it will really eat. but thats just mho and i'll admit im no big fan of the "baby cams" so that probably supports my bias, i also agree that a custom grind is gonna be your best bet.

Off the shelf I always recommend the Lingenfelter 211/219 which has .533" int and .560" exh lift with 1.6s and is on a 112lsa...next I like the CC503 also with 1.6s and after that I'd look custom...Either way I dont recommend over 220ish int duration and 230ish exh...just a personal preference...I've put many cars on the trailer with a lot more cam than I have...the big thing here is to match the cam to the head flow to the converter to the rear gear...

Wow... Looks like a lot was said while I was away... I talked to Jeff at thunder racing today, and he recommended for me the cc503 part number 07-503-8. He says the key to my goal is the torque, not peak hp and that this cam will probably be best suited for me. any thoughts???

cc503 is what im going with this fall. i think its a great cam.

not to highjack the thread, but where does the cc306 peak in torque vs the cc503?

I would also like to know... but it's looking like I'm gonna go with the 503 as well...
