I have just about all of the bolt ons you can do to an LT1. I have started to think about doing a cam coming up pretty soon. My brother tells me to get a cc306. But i hear good things about the hotcam. I know that the cc306 makes more power and everything but is it streetable enough? I dont have enough money for heads AND cam, so i just want to do a cam. Would i even be able to do a 306 with out doing heads too? As always any imput appreciated.

For stock heads I wouldn't put a 306 in. A Comp 224/230 would be a good grind, it'll get you more horsepower than the hotcam and its just as streetable.

 

Another vote for the XE 224/230 grind. If your even considering the cc306 the hotcam is probably too small for you. The cc306 IMO isnt very streetable, the power isnt where it needs to be on the street, but then again how much power do you need on the street? From what I hear the 224/230 hits a sweet spot, I am going to use this cam with ported heads however but it can be used with either.

 

Will that 224/230 pass smog as easy as a tuned hot cam?

 

emissions? I dont know, it would be close. Really depends on the tuning. There is a program out there to help a cammed car pass emissions. If you have a cable that might work.

 

I have seen both hotcam and 306 cars dyno with stock heads, different bolt-ons and for the street, the hotcam had a much better torque curve (very flat) so i would say it was more streetable. However, the cc306 had some great top end power....so. Different strokes for different folks!!! Either way you will have a cam!!!

 

i have sen the 306 pass emisions wuth good tunning. so with that i say get the 236/236 on a 114 lsa. works great with stock heads and even better with ported heads. so if the the 306 can pass so can the 230/236.... just my opinion.

 

The xe 224/230 will pass no problem, you'll be lucky to get the 306 to pass.

 

I'vs seen people have problems getting the xe503 to pass emissions. There is someone on this board that failed with the cc305 on a 112 LSA. You probobly won't pass emissions with a LSA less then 114, but that is JMO from what I've seen. xxsaint69x is running the cc306 on stock heads. You might want to talk to him and see what he says. He has run a best of 12.7@115.

 

I considered doing a 306 cam swap after I do headers and RR also. I have stock heads now, but want to upgrade in the future and dont want to have to do 2 cam swaps, one for stock heads and then again with ported LT4s in a few years. Can I run the 306 on stock heads and still get a decent power increase? I know it wont realize the full potential of the cam with stock heads, but I have to do one thing at a time.

 

a cc306 passing emissions is like a handful vs. the millions. Also take into coniderations Emissions differe from state to state. Some haveing VERY restictive, to some that dont have it at all, and some in the middle. It all varies.

I have a hot cam, and its totally where it needs to be, it makes power from idle to 6300/6400 rpm's. Most peoples rotating assemblies (stock) cannot rev any higher with out fear of lifter collapse, or breaking an internal.

My Nu-tek stroker project has components that will spin up to 7500 rpm's reliably, but my engine guy recommend with the given cam (LT4 HC) to spin no more than 6,300/6,400 cus the cam will not make much more after that. Unless a SC'er was added, I wish i had the dyno sheet cus a local shop just assembed a 383, LT4 HC, Vortec SC, every bolt on, F.A.S.T. engine management, and spun it up to like 7000 and it was still MAKING POWER!! lol.

So how much better is a cc306, hell it may go up to 8,000 and make power. But for the street we go from idle to bout 6,500 rpms MAX and most times it more toward 5800-6,100. ANd this is where the cam needs to be.

So long story short, HOT CAM ALL THE WAY. And it will pass emission as long as tuning is good. I live in CT and emissions are somewhat strict, so im glad i have that. IF you wanted another choice XE grinds rock too!

 

In TX it has been passed on the idle, no load test with a set of FLP headers. I dont know the variance in TX emissions other than some test, some dont.

 

i totally agree

but the 230/236 will make more power at 6500 then the hot cam will. and when you add the head work theres alot more to be had there. dont get me wrong the hot cam is a good cam but if hes considering a 306 he must want somthing big. but the 230/236 works better with stock heads than the 306 and really opens up with head work, and still helps you out down low.

 

I have heard that the XE cams are hard on the valvetrain. Is this true? From what yall say the xe 224/230 would be good for stock heads right? If so i think that is what i will go with. Would that be a good combo? What size roller rockers? 1.6? Thanks again.

Bro, the cam I was considering before I sold you the car is the gm 846. It might be something to consider. Its a 222/230 112 lsa and the lift #s are 542/563 with the 1.6 rockers.(If I can work a calculator tonight ) This cam might be a good compromise to the hotcam., but not quite as ballsy as the 306.
