402, IM NEW TO THIS! help please :)

It is fairly easy to get these little 318s over 300 hp fairly easily depending on what heads you have and compression ratio. Cam, intake, carb and a decent set of heads will help. Magnum heads are a good swap and bump up the compression ratio a little with the closed chamber design and came stock with 1.6 rockers. My little 318 in my dart screams and suprises everyone that has ridden in my car.
