My car weighs about 3600lbs with fuel and driver. I want a streetable cam that has power off of the line, but makes good power to about 6200.
I have a
58mm TB
Electric H20 pump
7/16 1.6 ratio NSA Comp Pro Mag rocker arms
1 3/4" primary Long tubes
3" collectors and 3" high flow cats
Smallest size pipe in my exhaust is 2 1/2" most of it is 2 3/4"
2800 stall converter with lockup
4L60E
3.45 rear end gears
285/40/17 tires



Here are my approximate flow numbers:

Valve life .100 .200 .300 .400 .500 .600 .700
Intake 70 146 202 244 269 275 273
Exhaust 60 116 153 172 187 193 196

What is your suggestion for a cam IE what cam would you run?

 

cc503

I think you would like the new XFI cam from comp. the number is 07-467-8. That would work great with the beehive springs.

 

Cc503

 

What type of times are you running with your current combo?

 

I don't go to the track! I am just trying to have a decent street car.
How's the 503 compare to the 305 and 306?
Looking at the CC chart it looks like it is a step down from the 305, but I am not a cam expert.
I'll check out the 07-467-8

cc503 ?? His heads flows 275cfm @ .600 I think he deserves bigger than 503 CC306 (230/244) or GM847 (234/242) would be better I think.

 

Seems several of you are missing the details I highlighted.

I might try one of the XFI grinds under 220 on the intake

 

So?

I know lots of people use GM847 for their street car. If bigger than 220 is not for daily car there would be a serious problem here

 

how about the power off the line with just a 2800 and only looking to go to about 6200. The 847 fit those criteria too?

 

Peak at 6200.... he doesnt wanna spin this motor to the moon. CC503 and dont look back. I think its actually a step up from the 305. Duration is the key.

 

Thanks for all of the input. I probably added a false premise. I don't mind spinning past 6200. I was trying to show that, I would rather have solid power across the rpm range vice a strip only cam that had a 3800-7500 power band.
Sorry if that caused any problems. I believe that I want something hotter than a hotcam/ CC305; looking at the CC website the 305's operating range is 1500-5500.

Thanks, how does it compare to the 847 and will it idle?

 

just do a custom cam. your going to get the most out of it, and still be streetable.
your heads flow pretty damn good so your not going to have to run a huge cam to get decent power out of it.

i would just call up one of the many companies that can grind a cam, and just tell them what you told us.
you wont be disapointed

i have a custom from http://www.futralmotorsports.com/
similar to the 306 i replaced it with, but made alot more power
