If you went with the 306 and a nice set of ported heads you would be over that 360 mark. The 847 would get you 360 and much more I believe. Im probably going to see 340~350rwhp with stock heads and the 306 (that tends to be the norm from what Ive seen)

 

heres a short idle movie of my 224/230...

Thank you very much. To get 400rwhp you really need a bigger cam than a hot cam. 400rwhp isn't that uncommon on here. I need to go back to the dyno but i hope to be close to that. Good ported heads with a 230/236, GM847, CC306 or a good custom cam will get you very close or 400rwhp. www.advancedinduction.com has several cars listed on his site with 400+rwhp on stock shortblocks with heads and cam. Some of them with shortie headers. Good ported heads and a hotcam will get you 350+rwhp. Asing if you can run low 12's is kind of a loaded question. That depends on traction, driving skill, race weight as well as hp.

 

to put your mind at ease..I am daily driving the 306 and I love it...

3:42s and a 2200 stall.. no complaints..and Im still untuned

 

it seems like you want a magic cam that gives good fuel milage, makes great power all across the RPM band, and has a radical lope. there is no magic cam that can do that. if you want to maximize power across the RPM range, get your heads flowed and get a cam custom ground to those flow numbers.
if you want 400RWHP, then you need to talk to either Advanced Induction or Lloyd Elliot. they both have head/cam packages proven to make 400+RWHP. just remember that along with it comes supporting mods, headers, rocker arms, new clutch/stall converter, rear end, and a nice computer tune. its not cheap. if you are just looking for a cam that you can throw into a basically stock motor with minimal mods (headers, catback, cold air) i would look at the 218/224 or the hotcam.

if all you care about is lope, throw a GM847 cam in there and a good tune and lope away.

 

Select cam because of sound , that's funny...............cause that's what I did!! I can understand why you want the sound. As you can see in the sig, I have the cc306. I LOVE the cams power and sound. Most say it has no power down low but I don't see how they figure that. It may be that my stall (converter) is helping me to get to the power band I don't know but it has VERY good bottom end for me.

 

It seems to me like you have in a sense, contradicted yourself. You originally wanted a cam that had an awesome lope, which I totally understand, theres nothing like it. However, then you say you want to get low 12's with a cam. Based on that criteria, the cam with the best sound isnt necessarily going to get you there. And then you throw ported heads into the mix. It seems like you are jumping all over the place. If you have originally posted that you wanted a cam that worked well with ported heads, gave good power, wasnt too horrible on gas, and had a good sound, some of the answers you got might be different. Custom cams are the way to go if you are getting your heads ported. They are customized to your heads, plus, you can request certain traits you want in your cam.

 

I have the XE comp 233/239 112lsa cam and it chops pretty nicely. sounds good through the hooker catback and longtubes as well.

just my $0.02.

 

First off Mike, you never want to buy a cam based solely on sound. If you do, you'll go to big and not have any power except in higher rpms with no torque down low and alot of cam surge. A lopey car sounds awesome, especially on true dual cars dumped at the axle. Since you want a cam that gives good power at lower rpms, you are not going to want a 306 or an 847. Even with a good tune, they'll still surge and not have much below 2500. Some people don't mind, me being one of those. If you're looking for that lopey sound, go with a middle of the road cam and set your idle at around 700rpm. That said, I bet you'll be very happy with a Comp XE 224/230. You'll have a nice broad power band and still pull well a little past 6k.

That sounds exactly like my car...exhaust and all...its get a pretty choopy/lopey idle and itll run cold at 500 rpms untill it gets up to temp then it idle at 750...the link is above a few posts

 

Is it considered a big cam when you can count the cylinders firing at an 1100 RPM idle?

 

no.

 

How about something with durations larger than 250* @ 0.050"? That considered a big cam to you?

 

Can you guys compare and contrast the hotcam and the xe 224/230 compare sound and performance. (both on 112LSA)
