stock 5.2 magnum power

Your not going to make 350 with the stock cam unless you hit it with NOS. It'll take a pretty big upgrade on the cam to make 350. The 360 mag has more cubes and only makes about 300 hp in stock form when converted to a carb. With headers and good or open exhaust, the right intake and carb and the timing dialed in you might make 350 hp with stock heads but your gonna give up a lot of low end torque doing it. I'm not bashing 318's but IMO if you want that much hp and keep it streetable do a 360. You'll make your mark easier with less cam so it'll have a lot more torque which is what you need in a street car. 300-320 hp is a more realistic # for a 318 if you truly want it to be streetable
