What cam to use?

[mykle]

Trying to find the balance between the good stuff and the wallet, so hoping to use as much of what already exists as is possible, the possible solution seems to be in the cam, I don't know what it is just that is was a circle track grind.
The rest...
350 4bolt .30 over
forged pistons approx 1/8" dome (approx 205 psi on comp test currently)
reportedly balanced and blue printed forged everything in the bottom end and 7000+rpm capable, I can't verify any of that though
weiland intake, single plain
holley 750 double pump
HEI dist with a coil upgrade
aluminum heads 2.02/1.60, 190cc intake, 64cc chambers
1.6 roller rockers
TH400, (I think a standard stall)
3.73 rear

I know it will take a large cam to make the combo work, but what we have now is basically not streetable, brakes are nearly non existant(it has a vacuum can as well), it won't idle etc. 7psi vacuum at 1300rpm. What are my options? cam? 2800 stall? We have pulled the intake thinking maybe it has a vacuum leak.

Thankyou,
Mike
