Do you think a 110LSA on a 230/236 would be too choppy or too aggressive on a street car? I would be getting a dynotune so that would probably take care of some of the roughness. Is anyone running this combo?

Thanks,

That's the same cam I'm looking at with the 112 LSA though. I'm still learning cam 101, but will be doing the dyno tune as well. I'm not doing the cam until heads next year tax-refund time. I've heard this is a nasty cam though . Keep me posted on what you find out on the 110 LSA, PM me because I'd also like to get more out of it if not just get a match custom grind.

 

That's a pretty big cam (230/236/112)....might need to really rev that bad boy to see peak power, probably past 6500. Start saving for a rebuild IMO.

hmm....that' s interesting because this cam from what I've read, heard, etc had the more balanced rpm range I was looking for at the lower, mid and high rpm range. Unless I'm being given bad information. I didn't want a cam that ran like crap until the high rpm and out of the 305, 306, 224/230 cam, etc this one had the correct balance.

I think I'm just going to call Competition Cams Hotline they advertise, tell them my setup, heads, stroker, goals, etc and see what the real experts have to say.

 

I have heard this is one of the best cams if you don't want to rev that high and you have a stock bottomend. Most people upgrade there valvetrain in the process anyway. This is a mild cam compared to the CC306, GM847 and such. Just need to figure out the right LSA for me.

 

Why do people say this? I have this cam and it's a blast to drive. It makes over 300 ft-lbs of torque from 2,500 to over 6,000 rpm. It's a very flat curve with no disernable peak. The horsepower builds almost in a straight line. If you compare it to stock, it makes more power anywhere above 2,000 rpm.

 

I don't see how the 230/236 is mild compared to the 306? Are you just looking at the lift or what?

CC 306 - 230 / 244, .510 / .540 112 LSA

CC 230 - 230 / 236, .510 / .520 112 LSA

 

I can give you some usefull info on this cam and why NOT to go with a 111 or 110 LSA. My dyno resuilts with this cam proved to be very interesting along with my friends resuilts on a larger XE grind cam. My peak HP of 340 rw toped out at 6000 rpm which is a very small but "bang on" power band where as other cams continue making power in the higher rpm. To plain and simply sum it up the XE cam 3300 series lobes, (not to sure about the number ) cannot make power any higher then that rpm range.

Here comes the idea of cam theory about pushing the powerband up higher by incresing the LSA and sacrificing your bottom end power to push the power band up higher. The lobes simply do not make any power past that point, perhaps you'd be able to push it a few more rpm higher but you would probably see worse resuilts by doing so. In my opinion 112 LSA is the optimal lobe seperation on the XE cams for a N/A setup, depending on duration/lift numbers of course but in the case of the 230/236 i'd say 112.

Hope that provided you with some helpfull info.

 

a buddy of mine has this cam on a 112 but said he wish he would have went 110,

the 110 is going to move the hp curve up to a higher rpm range (maybe 200 or 300rpms higher) and it will narrow the hp curve as well (about 300 or 400 rpms.

so if you peak at 6000 on a 112 you may peak at 6200 or so on a 110, and if i starts at 2500 and stops a 6000 (on a 112) you may get 300 to 6300 on a 110.

the 110 will also lope a bit more and is ussually harder to tune. and you will see more cam surge as well.

but it will yeild about 6 to 7 hp from going to a 110 over 112.

if you intend on spraying stay with a 112 or higher but you can spray on a 110 as well but you will gain more from your spray by going with a 112

this is just some things that may help you make a decision. remember these are NOT accuall #s these are just examples to help you see what im talking about.

but as for me im going XE 233/239 on a 110 with about a .569/577 lift. here is a great site. to look at cams and whats avalible...here

 

No, this is where you are WRONG! The HP drop after 6000 rpm is ridiculously large! After 6000 rpm at 340, by 6600 rpm i'm doing 146 hp.

The only thing you are going to end up narrowing is your HP numbers.

 

MAN that sounds like an awesome cam....I gotta check this one out..thanks.

 

im not calling you wong, nor am i a cam expert but, i have seen a 110 put down just alittle more than a 112 countless tmes. and there is a person on here (just read it the other day that is runing a 236/242 on a 110 and put down 383 rwhp on mid lenghts, and ported heads. and i think hea made it at 6600. ill try to find the post.

also i read countless times that the 230 236 falls off at about 6200 hundered on the dyno. why would yours fall at 6000.

an dyes i have heard that after they hit there peek they fall fast.

 

I have the 230/236 at 112lsa and it falls off shortly after 6k rpm, another guy here, shawn95z28 has that cam at 110lsa and double springs where mine are single and his falls off after 6k as well. Its either the cam or I read once where the GM engineers found that the LT1 rings would "flutter" badly at that higher rpm and consequently redesigned the LT4 rings.

 

What springs did you go with when you installed the XE 230/236?

 

Yeah, if you can find that thread that would be great. My friend dynoed hes 236/242 on a 112 and he toped of at 5900 @ 375 hp.
