360 build

i am currently rebuild a 71 dart swinger it had a slant six . i'm looking to get 400-450 hp out of the 360 along with a 100 shot of nitrous.i had the block freshind up and i am going to use the stock crank and rods with 10 to1 compression forged pistons. i was told by many mopar buffs that the stock crank and rods along with being redone would hold up to 400-450hp. also going to put aluminum heads on it . just wondering if the numbers i want to see for hp and tq will be hit 500hp and 450tq. not sure what cam and valve train to use to get those numbers any help would be appricated.
gotta shut this mustang up that lives down the street... ha ha ha
