im looking at a cc 306 cam i was looking at the 305 but this one is bigger and wanted to see if id have to have a vacuum booster for this cam or ever the 305?

does comp cams sel a kit with v-springs lifters and cam?
thanks
any suggestions on other cams for a bolt-on lt1 6-speed let meknow what u have.
* will these springs fit a lt1? K motion valve springs #k1200

 

Are you going to have the heads ported? Are you going to use a different stall converter?

 

eventualy they will be ported but its a 6-speed.

 

My bad I didn't see the part where the car is a 6 speed I'm a little drunk. As for your cam situation the cc503 is a very good proven cam for stock heads. How much do you plan on having your heads ported and when you say eventually in how much time? The cc306 will work with stock heads but it wont be living up to its potential

 

in the next 6 months or so. honestly im not good with the whole port thing. i was gonna try and get as much out of them as the shop can. (they are gaskets port matched now.) i wanting to use ether. i didnt wanna pay 700$ for the kit though. what all has to be replaced? i know the valve springs (whatsthe cheapest springs i can run?) but what else do i "have" to upgrade?
thanks for the help

 

The CC306 is an okay cam with GOOD fully ported heads, but for what you're looking for it's a poor choice.

If you don't have the money to do it right I wouldn't do it at all. A cam swap is fairly involved, and the valve springs aren't something you want to get the "cheapest". You're looking at the cam, rockers, pushrods, guideplates, lifters, timing chain, and most importantly a TUNE. A few of those things listed are optional but highly recommended. You may want to reconsider having the heads done for such a budgeted price. Many times shops don't know what they are doing and the heads will end up performing the same as stock, if not worse.

Consider saving up a bit more money - you'll thank yourself in the long run.

 

if a ran the cc305 instead of 306 would the b eehive springs work or do i need better?

 

IMO forget both of those. If you want a shelf Comp cam do the 503, your stock original lifters are probably just fine.

 

if i used the cc503 would the valve springs be okay untill i have cash to replace them?

 

The stock springs aren't really good enough for the stock cam, you absolutely have to replace them with any upgraded cam.

 

will these valve springs work with the cc305 cam? i have nio clue how to tell and some of you guys are really good at this. thanks

The 305 is a **** cam.. go 503 if you want off the shelf. And a set of comp behives will work fine. The 503 is an awesome cam on stock and ported heads... ignore the 305... take a look at some of advanced induction cams and Lloyd Elliot cams also...

 

will the ls6 springs work with the cc305? thats my biggest question guys.

 

Yes. But why are you set on a cam that isn't going to perform as well as the 503? Trust me I had the 503 and it was awesome!

 

nothing against the 503. i just ordered a 305 for a project a while back and just decided to use it a day or so ago.
but thanks ima go with the ls6 springs.
