Ok, ive heard LS7 lifters will fit in the LTX,
1 question. is this true?

2 question. what size pushrods will i need?

3 question. what springs will i need?

4 question. which cam puts down better numbers? the cc306 or the 227?

5 question. kinda newbish, what kinda hp would i put down with a cam only car?

thanks

 

1. Yes they will fit but don't bother if doing a small cam.

2. see answer to number 1

3. have to pick the cam first

4. define better and what numbers are you asking about, dyno and track are not the same. The 306 is bigger than should be used in a stock shortblock, the 227 is about as small as is worth the effort to swap too and is worth the effort. You somehow said small yet named cams on opposite ends of the spectrum. This should tell you something about the sources you are using for info. You need to spend more time here and figure out WHO knows what they are talking about before you start trusting information they provide.

5. you want HP numbers or track numbers, not necessarily the same thing. You want to go fast a mild cam can make that happen, you want a big dyno number and you will likely have to convince yourself that the "highway performance" makes up for the crappy track times.

Put it this way, the 306 is more cam than I am running. I would call it an outright bad choice particularly for stock heads, compression and displacement.

 

I would suggest you start reading up because the 227 and cc306 are complete opposites and cannot be compared. One will make alot more peak hp while the other wont but will have much more bottom end. One you will have to rev to the moon and risk your shortblock's life and the other you wont. Like Caprice said in a nutshell, its track times that matter not dyno numbers, too many people are dyno queens. My guide at the top of the forum would be a good place to start. All your questions regarding valvetrain will be in there also. As for pushrods you will want stock 7.200" in length. Springs will be determined after you pick a cam out.

 

heres what i found on the 227,

Crane 227: (210/224 .511/.553 112lsa) w/1.6RR's
Very good proven performer on stock heads. Stock LT1 heads have very restrictive exhaust ports relative to the intake ports. The 227's wide split in duration helps balance that out. The 227's low-end power starts low and is consistent through the entire mid-range. Known to be a torque monster with great drivability. Held a cam-only record for quite some time.
Pass Emissions?: Yes
Shift Point for Maximum Performance: 6100-6200rpm
Idle Characteristics: Smooth Idle with a Slight Lope
M6; Require Gears?: No
A4; Require Stall?: 2500+ Stall Speed

found nothing on the 306

and then another cam i thought about

cc503: (224/230 .535/.544 112lsa) w/ 1.6RR's
Widely known for being the biggest cam you want to run on a stock headed car without sacrificing usable power and drivability. Has a strong mid-range with good top-end power. Features Comp's XE (Xtreme Energy) lobes for more top-end power. Will have some cam surge.
Pass Emissions?: No, requires tuning to pass.
Shift Point for Maximum Performance: 6400-6500rpm
Idle Characteristics: Choppy Idle
M6; Require Gears?: No
A4; Require Stall?: 2500+ Stall Speed

i just want a good performing cam, hp wise and time wise, fuel consumption/emissions = nothing to me. and i would prefer not to spin the engine over 62-6400

LPE 219/219: (219/219 .560/.560 112lsa) w/ 1.6RR's
Known to be a great performing cam with awesome drivability. Quite torquey in the mid-range and top-end with a strong mid-range power band. Developed with the TPI motors in mind which explains the single pattern duration. LT1's prefer more duration on the exhaust side so the split-duration 211/219 may be a better choice.
Pass Emissions?: Yes
Shift Point for Maximum Performance: 6100-6200rpm
Idle Characteristics: Fair Idle with a Slight Lope
M6; Require Gears?: No
A4; Require Stall?: 2600+ Stall Speed
^^think i found my winner(s) either the 219/219 or the cc503 or maybe the 211/219

 

Reason the cc306 is not on my guide is because I do not recommend it to be run on stock shortblock safely and most people are not willing to shift up to 6700rpm. I would recommend the 211/219 before the 219/219 because the 219/219 was developed more with the TPI motors in mind and LT1 motors prefer split duration camshafts with more duration on the exhaust side because the exhaust ports are restrictive relative to the intake ports. The 227 and the 211/219 will offer the same performance and characteristics. The cc503 is a noticible step up from them. Anyone of those cam will pass emissions with tuning and I know you said that doesn't matter nor gas mileage. You said your willing to shift upwards of 6200-6400rpm. In that case the cc503 would give your car the most peak power and run the fastest times assuming the car is properly setup and you shift at 6300/6400ish. I run the cc503 and like it very much. The car put down 330 through the automatic with full exhaust and rockers. The car also runs very well at the track, however I am swapping it out for a custom grind next month. A custom grind would be something to ponder, mine is going to run me $360 with shipping. The Crane 227 or LPE 211/219 will run that much. The cc503 will run around $250. So if your willing to spend that much for the LPE or Crane cam I'd just go the custom route. Might be worthwile to check out Advanced Induction site for their grinds, costly at $400 but seem like good performers and are billet hence the cost.
Would help if you would list more of what you want, what kind of gearing or stall size do you want to run? what kind of track times are you looking for? Is cam surge an issue? What kind of idle do you want? etc. etc.

 

thanks a lot, i had just heard good storys from people running the cc306 and thought it would be better than the 503.

and one more question for you, would it be alright to get the LS7 lifters and then what springs? and will i still be able to use the 7.2" pushrods? i THINK that covers it, for now anyways, besides the hp #'s with the 503.

 

I edited my post so check that out. LS7 lifters will be fine, will work fine with 7.2" Pushrods. I know in some threads people have questioned that but people are running the LS7's with stock pushrods and have been good to go. Spring wise you have a few options. Check out some of them in the guide. I personally run the Crane 10308-1 kit that can handle up to a .600" lift. People have been very successful running the cc306 but its not really a daily driver friendly cam and they are succesful with it because they are shifting where they should be 6700-6800rpm. A car with the cc306 shifting where it should with the right setup will out perform a car with the cc503 at the track but ONLY if its being shifted at where it needs to be. The cc503 shifting at 6400rpm will hand the cc306's *** if the cc306 is shifting at say 6200rpm.

 

im planning on a cai, headers, ory, i like the stock gearing but i might change them, cam surge is not a problem, idle isnt a problem as long as it idles on its own, and judging by porksoda's sound clips, i like the sound of the 503, so thanks for your help, i think i found what i want.

 

no problem. go on youtube and search for cammin ws6 or search for videos under my username, I have several clips of my car idling if you want to see more.

 

oh ummm, would you be willing to get rid of your cam next month and if so....can you pm me the information about it, like how many miles etc etc etc and then how much you would like to sell it for?

 

do you already know what the spec's are on the custom cam that you plan on swaping too?

 

I haven't been told them yet and cant give them out when I do know but I do know that it is infact similar to the cc503 duration wise with a tighter lobe separation and will be tailored to my 3600 stall and 3.73's.

 

There are a lot of good stories with the 306 because it has worked well for a lot people. It may not be ideal for stock heads though, but it's still not a terrible choice despite what some people say. It has been more than proven to work.

 

ok does anyone have the part number for the cc503?

 

Part # 07-503-8
Grind Number is LT1 XR276HR-12

 

sounds liek you know your stuff...you will probably be getting some pm's from me in the future when i start down the road of camming, haha! and how is your 3600 stall as a daily driver? i got 3:42's and will probably stall mine next

 

haha sounds good! The stall is great I absolutely love it. It drives fairly stock and it really makes the car a blast to drive. The performance improvement was very noticible, Id highly recommend the SS3600 to you especially if your planning on camming it in the future.

 

great! thanks for the info! i'll definitely be keeping in touch with ya!
