upgrading my 360

hopefully by this weekend i'll have my duster sold and with the extra cash im planing on fixing my dart it has a 88 360 motor in it and its pretty much new but it has a R/V style cam im wanting to wake it up alittle more so far my motor has a 650 thunder series eldebrock carb and a performer 318/360 intake, headers, 904 trans with a high performace valve body stock stall and a 8 3/4 rear 3:23's. i also have a M1 single plain intake aswell but i want to be able to drive my car on a regular basis. so far i've selected a cam kit from summit K20-223-3 im thinking this is the 268XE not sure though.
i'd like to get a noticible cam sound and very responsive
thanks for any imput
