Cam choice-stock heads Ok to start off I have read the sticky and did a search but cant seem to make up my mind on which i should really go with, so heres what i have so far....
Ok so i pretty much have things picked out that i want to add to the motor other than valve springs and cam.
1.6 rockers and ewp are on the car, to that im adding pacesetter lts, different catback, prolly true dual, progear timing set, march underdrive pulley set and either a ported stocker tb or a 52mm unit. The car is going to see about 4k miles a year but with 3-5 trips to the track each month and i want to try out some autocross with it. As I said before id like a good midrange but a good idle, nothing to choppy where it feels like it will die but a good strong lope isnt a problem. I did research on the crane 227 and it seems like people are happy with it, good low and midrange power and pulls good up to 6k. So it sounds like what id want but it looks to be one of the smaller cams and i dont want to settle for it if i can make more overall power with a diff cam with only a slight trade off with less low end power. Also valve springs, heard comps been having quality control problems so need a good alternative to they're beehive springs. Long read but hope you can give some incite on whats a good choice for my goals.

thats stuff for predicted power and torque which isn't acurate just fill in the application and short block section for cam suggestions. trust me i tried to get the predicted power but it doesn't work.

Edit: Nevermind. I changed the type of cam I was looking for to "Overall street performance with mild-rough lope." And it put me back into my predicament of choosing cams. I'm still stuck between the CC503 and CC305(112 LSA).

lol. Yeah, I was doing all that stuff, just to see what cam would give me the best power gains. I just put the lowest CFM choice it had. It's saying that the cam that will give me the most power will only put me at around 310rwhp, but around 460-470 lbft of torque. It is telling me that this cam will give me the most power, with my stock heads. http://store.summitracing.com/partde...t=cca-07-465-8. I'd never seen that cam before.

If your gonna autocross I would think the Crane 227 (210/224) would be a good choice because of the strong bottom end and mid range. Just because its small in duration doesn't mean it wont perform. Maybe check out the AI 218/226 cam, its a little bit bigger and may be towards the size of what your looking for. Its very similar to the lt4 hot cam but much better, said to make another 15ft./lbs of torque.

The only thing that turns me off about the CC503 is that it needs to be revved higher than the CC305, to get its peak performance. And revving passed 6,000rpm on stock internals scares me a little. I guess I should be fine as long as I get some pretty good valve springs, lifters, and pushrods though, right? And how do I find out the max lift of valve springs? I was looking on Summit for some new springs once I get some RR's, and none of them had listed what their max lift was.

If I was you I wouldn't worry about shifting past 6000rpm. I believe that up to 6300 is safe without any worries and if you had the cc503 and shifted at 6300 the car would most definetly run like a ****. I was trapping over 110mph through an automatic shifting at only 6000-6100 with the cc503. The more aggressive lobes of the cc503 are better than the older magnum lobes of the cc305 which partly is why it makes more power than the 305. Sorry cant answer your spring question. I have the Crane 10308-1 kit and they are good up to a .600" lift fyi. If you want part numbers for all the valvetrain stuff you will need shoot me a PM, Lloyd Elliot was kind enough to supply me with them.

That kit would probably be good enough. Because, with 1.6rr's, a CC503 is only .537/.544. Even if I decided to go with the 1.7's I was looking at, I wouldn't have a problem with going over .600 for lift. Did the Crane spring kt you bought, come with the locks and retainers too?
