With the dual quads, a tight lobe separation will work really well.  It will have a very choppy idle, and the tight lobe separation will really pick up the midrange.  Comp cams has a 'Thumper' line that should work really well.  Most have a 106 degree lobe separation.  What kind of rpm do you want to turn?  

What type of cam are you looking for?  I'm guessing a hydraulic roller?  If it's a toy, you may want to consider either a solid flat tappet, or a solid roller...  and let it spin around 7k rpm.  If you want to do that, a solid cam around 238-240 degrees @ 0.050 on the intake, and a little more on the exhaust with that lobe separation should make for a fun engine.

If you go solid roller, make sure you use a compatible distributor gear.  
flat tappet solid/hyd iron dist. gear
hydraulic roller, melonized steel
solid roller, contact who makes the cam for what is compatible.

Gear will also need to be installed properly, and checked for the right depth.

Good Luck!

I'd talk with Mark at Bullet Cams.  Either that, or just go with a 'Thumper' from Comp.  If you're making the hydraulic work, that's an option.  They are just often problematic much over 6k rpm, unless it's 'right' and you've got good parts.  I like solid flat tappets in 289/302's.  That's what's in mine.  You just need to have good lifters, break it in right, and use a good oil designed for flat tappets.
