Small Block & Big Block Chevy Specific - need help pickin cam 350sb

this is my first time pickin a cam, and i dont know what to look for. i have a 69 350 with the stock rotating assembely, it has a set of camel hump heads, alumnium duel plane intake with a 750 holley vacume secondary carb. it also has a 350 tubro trans with stock stall and a 12 bolt rear with 4:56 gears. im going to use the car in an 1/8 mile track and i dont want to change my stall and would like for it to have a good sound if possible

would a cam with a 218/230 duration(0.050-inch) and a .462/.480 lift and a lope ceterline of 113.0 and intake centerline of 108.0 work with out runnin a stall or changing my valve springs and would it still draw enough vacume to work my brakes and my carb

Seems like it would work. I day 224 intkle 230 exh. Around 500 lift is good and a 110 LSA.

any idea on the specs of what's in it now?

it just has the stock cam right now
