Indy intake and TTI 2 inch, stepped I think.
I was thinking about a comp 308R(575 lift roller)

308 is a lot of duration for the street I think, even at that displacement. To be clear the 308R on COMPs site is a 650+ lift lobe, not the 575 you've mentioned.
The better your heads the less I'd try to cover it up with such a big CAM. You'd do better with a smaller CAM overall. I see the next step down in size is a 292R though and that might be a great street strip CAM, but might be leaving a small bit of potential on the table. But a 308R might kill enough bottom end, idle and other street characteristics that you might not end up liking it. COMP recommend 12+ compression with that CAM, where as they like 10.5 for the 292R. I and a number of guys have run the 286R cam in small blocks and like it very well. While a 292R might also be streetable, I'd have to give up a decent idle speed to pick up a small bump in top end RPM range. Since you're heads are going to flow way better than mine, you might find that you don't need as much CAM to extract a great amount from that many cubes.
It's all subjective. What you consider streetable isn't neccessarily what others will think is streetable. If you can better quantify what matters to you for idle speed, temps, vacuum, exhaust noise etc. Maybe someone can do a better job helping you sort that out.

I see. You're looking at this one: http://www.compcams.com/Cam_Specs/CamDetails.aspx?csid=739&sb=1I was looking at this one: http://www.compcams.com/Cam_Specs/CamDetails.aspx?csid=744&sb=1The 292 I was referring to was actually the XR292R: http://www.compcams.com/Cam_Specs/CamDetails.aspx?csid=743&sb=1My mistake. The one you're looking at is just a less agressive ramp and probalby needs less springs etc. Personally I'd go for the more agressive ramp. You get more area under the lift curve, for the same or less seat to seat valve timing. The XR292R is spec'd slightly smaller, but lifts more and gets off the seat more quickly, having effectivley around the same overall area under the curve as the 3008R, and probalby make more power, and especially make more torque in the lower RPMS, idle better and pull more vacuum.

I currently run the XR286R in my challenger  car will go quicker as that is my first time out messing with the whole new setup.... so far my car et'd quicker shifting at 6000 instead of 6500 probably due to being a stroker.... Id say 6000 rpm is not beating on it at all  remember those cam car specs are for a 440 and a stroke will bring the powerband down a few hundred rpms....

The 292 street roller would be a good choice. I've run the 298 street roller and it makes great power in a 500 inch motor but the idle is pretty knarly. The 292 would tame down the idle a bit but still give you plenty of power. http://www.moparmusclemagazine.com/techa...lock/index.html

If you read the article you'll understand what a XR298 is.

Was this supposed to be for a nitrous motor? Sure looks like a nitrous grind to me.
I cant understand the wide LSA that some people like to grind for a na motor, doesnt make sense to me?
I was told by Dwayne that the Comp Magnum rollers are easy on parts, but arent that great of HP builders.
72 RR, Pump gas 440, 452s, 3800 lbs, Corked, ET Radials,. 11.33@117.72.

 If you wait too long, Chris'll buy that cam too! 
My cousin has that in his 440 Charger..runs mint, street car. He just peeled off an 11.1 out of the garage with some tuning left...

The Wider LSA flattens the torque curve, creates more top end power at expense of the pur peak power, improves vacuum and low RPM characteristics. Think of it as a more streetable version of the same CAM. I should note, my XR286R is a 112 LSA version that COMP ground for me per my order though Ou812 (aka brian). Brian was quite helpful in selecting that grind for me as well as input from other members that had been there done that.

Ya, I did buy it(575 lift) but its easy to change them. I like the one in the article so I will order that after I get the car running and do some testing with it first. BTW my engine was dynoed with a hydraulic roller 602HP/615TQ. That cam and it was dropping power after 6000rpm.

Well it was a big NOS cam that I ground smaller but tried the 114 for throttle responce and low end. (no not mine I'll never use NOS)seem to work good pulled good out the end. great throttlle responce and idle
reground another big NOS cam down to try now this one is 272/282 .650/.670 lift on a 110 lobe center.
.696/,715 lift with my 1.6's. lots of used NOS stuff as we know NOS motors rest in pieces!!!!
trying another

Was that at Bruces's? They always seem to show that the power is dropping before it really does in the car.... 
Bens 440 seems to keep pulling..,He's still shifting up past what the dyno said...

I just installed the 298r that Andy is speaking of in my 12.1 indy 440-1 headed 451. I just got the car up and running a week ago. Personnaly, I think the car idles pretty well, starts up pretty easy and sounds great.
