What cam should I get?

Big cam sound is contrary to your goal of "to just jump in and go up the road ". The big cam sound comes from a lot of over lap and duration. This makes for very inefficient cylinder filling at low rpms resulting in loss of power. Throw relatively low compression and small displacement into the mix and you make it even worse to the point the car is not driveable in traffic.

For your intended goal the Comp XE256H is likley the best choice and the XE262H would be the biggest you should go. Remember like carburators it's better to error on the small side than the big side.
