I can go a little higher but anyway if someone could give me some ideas on a good cam to use?
This is normally the point where I get a little blustery with the OP, but I will try to be civil this time.
Young man, you cannot intelligently choose any cam for any motor until you have determined the static compression ratio of the motor. To calculate the static compression ratio, I, we, you, will need the bore, stroke, piston deck height, head gasket dimensions, combustion chamber volume and piston crown configuration/volume.

You and every other Sonic Drive-In cowboy thinks he needs a cam that makes his daily driver sound like a Top Fuel car. You don't own a Top Fuel car. You own a daily driver. If you use a cam that makes your motor sound like a Top Fuel car, you have given up most of the qualities that would make a good street-driver motor in the first place.....good idle, good vacuum for brakes and/or other vacuum-operated accessories, low end power, etc. Many Ricky Racers before you have installed these Thumpr (tm) cams, only to yank them out when they find that the cam is all about a choppy idle and no real power.

If you'd like to list some of the components in the motor, we will do our best to determine the static compression ratio of your motor and suggest a range of cams or at least arm you with the info you need to talk intelligently with a tech at the cam grinder of your choice and ask them for a recommendation.

You can't just reach out into thin air and choose a cam. It doesn't work that way.
