What cam should i use?

The car is an 88 mustang gt. it has a 5 speed. also has gt40p heads untouched. explorer intake 411 gears and 150 shot nx kit. and slicks everything else is factory. yes i am running factory headers with gt40ps. im looking for any ideas on what cam i should run with this combo and what exhaust.

thanks for any help.
 
Truly a stock cam will work very well with that combo, I could recommend a few other cams but the gains will be minimal.... Swapping a nice mandrel bent header will give you some gains ;)
 
Leave the stock cam... I have a similar setup. I just bought different valvesprings a week ago for mine, so hopefully they work better than the stockers. Supposedly the stock ones suck.
