I don't normally recommend something like this but if your girlfriend really is expensive you may want to consider why she is with you. Would she stay if you didn't spend money on her? If so, she needs to go...

Anyway, cam size will affect your gas mileage but way less than how you drive it will. Put a decent cam in it now so you don't have to do it again later (and you will)

 

I run the 305 in my 383. I have emissions to deal with, so that's why I don't have a crazy cam. Goes good, even for 9.5:1 CR. No times yet, sorry.

Now I just need cash for the blower.

 

Actually good numbers can be achieved with a mild cam. Mine is a little smaller than the cc305 but has run pretty good nontheless. Like others have said, you definitely can go larger with a 383 and still have good driveability but make sure the cam matches your heads.

 

Can someone answer the question about the vaccum in the manifold?(Will the vaccum drop too much to opperate brakes, ect. if i put a say cc306 into it?) Im sure the HotCam Kit will make much better power than the stock cam my father suggested(LOL). I also have a 5-angle valve job and slightly ported. The stroker is built for durability(16 year old) and will also make PLENTY of HP to get myself into trouble. My motor is built using SCAT cast crank, forged h-beam rods, keith black pistions(clevite), the bottom end is balanced, shorty headers into full 3 inch catless system, 5-angle job with port work, Hotcam kit and a computer re-tune. Any estimates on HP? I know its hard to guess but i just cant see where putting in a cc306 will give me in excess of 20 more HP than the hotcam will give me. Thanks, Brian Kaiser

BTW, The girlfriend is a good girl and she always offers to pay her way but I guess I was brought up to pay for her.

 

Yes, your vecuum will be lower with a bigger cam, cc306. As you can see, there are a lot of guys running this cam with no problems, and it will also make a lot more hp.

If it was me, I would go with the cc305. There are a lot of guys running this cam and are putting up great #ers. You pick one used from this board. If in the off chance you are not happy with it. you can change it out over a weekend for the 306. Just make sure you are using the correct springs for both of them. Most of them go fast as you can see... http://web.camaross.com/forums/searc...by=&sortorder=

 

Are you guys insinuating that there will be a vast jump of power from the hotcam to a cc306? Im just looking to have a (mild) cam with some (mild) lope and give me a (mild) increse in power and still retain (mild) gas milage. I dont think that my car will be a dog with only a hotcam kit in it. With the mods that i listed in my last post, what do you guesstimate HP will be around?

 

OK I take back my comments then - I was brought up the same way

There will be a pretty substantial increase in power from a CC305/HOTcam to a CC306/XE230/236, but its all in what you want. The bigger cams won't idle as well, get as good gas mileage, won't pass emissions, etc.. A compromise might be something like a 224/230? In between the two your choosing but still a decent cam...

 

I haven't actually compared the 2, but I'm guessing the Hotcam would sound choppier, because it's cut on a 112 LSA. The CC305 is cut on a 114. The lower the LCA, the more radical the cam will sound. Yes, duration has alot to do with the idle charachterisics, too. The HC has less duration. They may even equal eachother in idle quality.
Anyone here heard both?

Just to set your mind at ease about the vacuum-

I run the 236/242 on a 110(!!!) LSA and my brakes and power accesories work fine. Though this cam is not for your needs- I still get 18 mpg on the highway(15 in town) and it lopes big time. Still very streetable IMO.


the 224/230 sounds better to me than any of the others mentioned. I thought my cam was gonna be too much after I ordered it....but the extra cubes really tame it down.

Good Luck on the build!

 

I already know that im going to go with the hotcam with my setup which includes SCAT cast crank, forged h-beam rods, keith black pistions(clevite), balanced assembly, shorty headers into full 3 inch catless system, 5-angle valve job with port work, Hotcam kit and a computer re-tune. Any guesses on HP? Im sure it will be rather high for a 16 year old.. I also replaced my clutch with a stock unit. Now all i gotta do is get some sticky tires and i will probably be into the 12 second range. I think the weakest link in my powertrain will be the clutch or rear-end. I plan on putting in a rear-end girdle and the clutch will be replaced if i fry it too soon. I also need a pair of sub-frame connectors. Other than that my assembly should be good to go.

 

The hotcam does have more lope to it. The cc305 sounds almost like a stock cam in a 383. The duration numbers of the 2 are pretty much the same. Biggest reason I like the 305 over the hotcam in the 383 is it has more lift to use the extra cubes.(.544 v .525 with 1.6rr).

 

I can make a guess of about 400-430 rwhp, but torque is what gets u going Last year at a show i was at i was looking at a guy's car that had forged crank, and 10.5 comp pistons. The cam was a lot bigger than the hot cam, though he wouldn't tell me specifics. he was making 538 hp on the squeeze (roughly75 hp shot) I hope you enjoy the setup, don't blow too many things up, it gets expensive really quick! Get back with some #'s!

p.s. this car was running 11's and had a lot of head work, and was shooting nitrous!

 

Im sure my HP and TORQUE will be up around 400 rwhp but my 1/4 mile times will be severely hampered by the fact that im just running a p245 tire. Im sure once i get traction the power will take me down the track in about high 12 seconds.

 

Sorry but I think that your expected rwhp is way too high.

 

If you want to see a dyno graph and some numbers with a CC305 in a 383, just send me an e-mail. This dyno test was done before I installed the Procharger. I had the engine built for low end torque. I would agree that you need more cam and better heads if mid and upper range hp are more important. Here is some info not listed in my sig:

CC305 112lsa 1.6rr's on intake/ 1.5rr's on exhaust
M6 when dyno was done/ 3.73 gear
30lb injectors
Electric water pump
Ed Wright mail order tune
54mm throttle body
Heads only lightly ported and polished (I think another 20 to 30 hp would have been possible with better heads, which now I think are really necessary for a stroker build up.)
