Need advice on best 302 cam combo

I need advice on the best stall/cam combo. I'd like to keep it as affordable as possible by using the parts that are already on the car. I plan to use the car more at the strip but may play a little on the street. I dont plan on flogging the nitrous all the time on the street though. I have the stock cam and a B303 cam. For the setup below, which is the better of the two cams? Also what stall should I run with either cam? I want it to pull the wheels at the track but still be atleast a little streetable. I have a built C4 but no transbrake.

This is the set-up as it stands:
302 - stock unrebuilt bottom end
E7 heads - look nicely ported with upgraded springs
1.7 Crane Cobra roller rockers
GT-40 Tubular intake with lower ported to match heads
70mm Edelbrock TB
C&L 73mm Mass Air
24lb injectors
March Ram Air
3.73 gear
100 shot nitrous
Canton oil pan
BBk headers with 1 chamber flows
No front accessories other than altenator

Thanks in advance for the input.

use the b303 cam, its more of a boost cam and itll rev up to 7k with no problems, as long as you use arp bolts. to pull the wheels off the ground it'll take over 400rwhp with proper suspension. Aint nothing cheap about that. you are a long way from even coming close to 400rwhp and when you get there youll snap the axles, twist the frame, brake a drive shaft, have braking problems, youll need a cage, helmet, belts, window net on and on... btw street racing is illegal

Not to sound so harsh, but I guess I was hoping for more advice and less sarchasm and criticism... "Seriously, gonna need more than that". I said it wasnt going to be used much on the street and never mentioned street racing. I'm not talking about packing the wheels, just pulling them at launch. As for the car not being able to...that is where you are wrong. I saw the car do it before I bought it...and it done it with the stock cam. It spun the input shaft in the convertor so I had the C4 tranny built with the best stuff Broader Performance has to offer. I plan on using the tranny behind a stroked windsor in the coupe I'm building, which is the main reason I dont want to spend alot of money on this car. Good heads for this motor would not be good heads for the stroker, etc etc etc. The car has the necessary suspension, tires, chassic stiffening, and spray to make up for what the motor lacks. I know that everything will have to be just right to make this happen and I'm not saying that something else wont break, but I'll deal with that when it happens. I just wanted some advice on either staying with the stock cam or could the much hated B303 cam help just a tad. All I hear is negative stuff about this cam, but for some reason a ton of folks use it and some use it effectively. I have both the cams, dont want to spend any additional money on this car for what it is, and I am limited by valve spring max lift...that is why I wanted some opinions on these cams and advice on appropriate stall. I figure the tubular intake and heads will be done around 5400-5500 but thought the added lift may help just a bit. Sorry for sounding off, but bashing someones $&*! when they're just looking for honest advice really pisses me off.

the 1.7's may not work with the b303 it has a lot of duration and the 1.7's are goining to put you over a 1/2" of lift i would check the piston to valve clearance. every motor is different, so it may be fine. as for the raising the wheels maybe with 4.56's and slicks
