Good 400+ HP 360 build

So I'm wanting to put a 360 into my 73 dart, I'll be putting an 8 3/4 with 3.55 gears and I'm not sure about what I'm going to do about the converter. But I'm wondering how I can get 400+ hp out of it without stroking or boring ,the car will be a street/strip car.


So basically you are just doing a cam change?

You want to keep your old pistons, rods, etc.? So what pistons are in there right now? What compression?
