Well I did want to go with the CC306 because I think it seems like a great cam and I love the sound of it. But I've been hearing so much about how the xe 230/236 is such a great cam. I've also heard good stuff about the 236/242. What would you guys recommend between the two? Current mods are in the sig. but with the cam install im going to do ported heads/intake. I want the car to be mainly a street/strip car. Something that is badass at the track and sounds mean, but yet is still street legal for cruising and occasional daily driving. Im not worried about emissions. Also, how much more HP would the 236/242 make over the 230/236? thanks

i would like to no this also. i think ive made my decision but im still not sure.

 

236/242 is too much for the street
idling at 750-800, i sometimes stall coming out of park.
video of it in my sig. it chops hard!
thats in a stroker that tames it a ton, I have stock heads (not for long!) which quiet it and it sounds a lot less noisy in the video than in real life

you can also take that cam to 6900 rpms or so, so the power might be out of reach on stock bottom end.
the 230/236 should rev to around 6500.
Id personally reccomend a 232/234 cam custom group with steep ramps.

What would really be the difference with the 232/234 vs 230/236? What would the difference in performance/ characteristics be? Im not worried about stalling it since I do have a 6spd. I want some that has a very choppy idle, but I dont want to have to spin much higher than 6500rpm either. Thanks

Aaron

PS. Trey your car sounds great!

 

If you're going to get your heads worked, just wait for the flow numbers and match your cam to them. I'm sure you could get close with a cam offered from Crane or CC, but you may have to go to custom grind to get the most performance.

 

thanks aaron
it really seems like a custom grind cam is best for you.

the 232/234 wouldn't rev much higher than the230/236 because there is more intake and less exhuast- but it should have more tq and bottom end thanks to the increase intake. It would be more choppy though.

it would be a median between 236/242 and 230/236
I'm still new to this cam stuff so I suggest you call combination motorsports. I dont think you can get better advice/price than that.

 

XE 230/236 is great for the street in a 350.

I wouldn't recommend the XE 236/242 for the street unless you were doing a 383 like Trey.

 

I will let you know how streetable it is soon enough.......SStupid is right. Check out the flow #'s of you heads first, then get the cam that matches it better.

I was lucky, I got the cam before the heads 230/236 which has a lift of .544/.555 I/E, and my heads flowed 258.5 Int. at .550, 198.X Exh at .550. After that, my flow number stayed steady, and actually lowered a little. So i was able to match the max lift on the cam to the peak flow of the head.

I recommend that route.

Good Luck

 

Why not just go with the CC306? As far as I have seen it has a bit more potential than the 230/236, it is streetable, but not too big for a 350. It is not as hard on the valvetrain and it doesn't peak as hard as the XE grinds. With the XE grinds you'd prolly want to dyno to know exactly where to shift at or you will prolly loose more power than you would normally if you rev past peak power.

I was in the same position as you, except I was choosing for my 383. I ended up going with the 306, the 230/236 **I** considered kinda small for what I wanted (for that matter the 306 seems more tame than I thought), and the 236/242, well I just didn't like the way it sounded at all (IMO). I am very happy with the 306, there is just a very slight bit of difference during daily driving than my hotcam, its really hard to notice. I can't get traction whatsoever nor can my fuel pump keep up, so I can't really say for full throttle.

If you really didn't want to go with the 306, then I would say the 230/236, it seems to be pretty driver friendly. I just didn't like the fact that they are hard on the valvetrain and I drive my car close to 600 miles a week.

 

hard on the drivetrain is a very relative phrase
its nothing stock GM lifters, pushrods and valves cant handle with their eyes closed

and if you chose a cam on the way it sounds ?
my car sounds pretty bad *** with Xe 236/242 (in sig)

the Xe WILL MAKE MORE POWER THAN THE 306
THE 306 WAS NOT MADE WITH LT1 IN MIND
IT BLEEDS OFF COMPRESSOIN WITH ITS LONG EXHUAST OPENING
AND DOESN'T ALLOW POWER TO BUILD TILL HIGH RPMS.
plain and simple.
Call up combo motorsports and ask them. I 100% promise they will tell you the same thing.

 

Yes, a factor in my choice of cams is how they sound no matter how ridiculous that sounds to you. I take pride in how my car sounds, and I'm not a huge fan of alot of lope. I like it but not all the time. Yes your car sounds bad ***, according to you. I think it was just the quality of the clip you used, but I really did not like it at all, my opinion. Oh well.

Stock lifters couldn't handle my hotcam for one, that's really all I can speak for.

FYI info I did call cmotorsports a few weeks ago and they mentioned the XE cams are harder than avg on the valvetrain. They also mentioned that the CC306 was designed to help the weak exhaust ports on the LT1, hence the longer exhaust duration. It makes plenty of power for me yet appeals to what I like a cam to sound like. If I want lope I open the cutout, if not I close it.

 

performance > sound

and once you get the heads worked, the Xe is a better choice

and uhhh what kind of cutout are you using?
since when does a cut out add durrration???

 

Ok, Trey if you say so. I came to state my opinion, not argue.

BTW I used the super duration adder power cutout+++ only $39.99. Call now.
Last I checked a muffler **muffles** the sound of the exhaust note therefore lessening the sound of lope. Guess things change though huh?

 

i think you would have liked the 230/236 on a 114 better has an ok lope but torqe at the bottom, and better the bottle than the 306, if you so choose to. just an opinion

 

I hate to bust into the arguments here, sheesh! I think Trey is only trying to help people from making bad decisions.

One trend I've been noticing lately, besides completely mismatched driving style, parts, etc. are people's complete disregard to drivability with cam choice. This is of course going to be the most noticable problem for anyone that has a street car. I have a hunch that most of these prospective buyers have no experience with cam'd cars, if you do and honestly want to go bigger than don't take offense. Bigger cams have more than just problems with emissions and fuel milage. I would hate to see someone throw in some ungodly sized cam only to find out they cannot stand the smell, the bucking and surging, the split BLM's and the nightmare tuning that follows and everything else that comes with a hefty cam.

A 236/242 on a 350 with stock heads is a very poor choice. It will not make the power you want as the heads will become a restriction before even getting close to the cam's powerband. It will have horrid manners on the street. As the car is bucking back and forth banging the hell out of the transmission and rear end, making all kinds of clanking noise, swapping valvesprings all the time, and making your drive miserable instead of enjoyable you will not think the lope is worth it. Dreaming and listening to sound clips is fun but you should get a *real* idea before diving in. Cams bring more to the table than a cool lope and high RPM power.

A 230/236 XE cam is as big as you probably want to go on the street. It will rev right into the mid/high 6k RPM range with good heads and a full exhaust. If you plan on getting some great heads but want the cam first you could run this cam with stock heads, it really won't live up to its potential this way though.
