I have a 72 Dart with a 318. Im looking for a good small block project to get some serious power. I was looking at two choices: 360/426 stroker from a block in my shed, or 318/390 from the motor in my car. the 360/426 is going to be a pricey endeavor so I was looking for info on the 318/390 project. Does anything need to be done to the block (notching, etc.)? Can any stock bottom end parts be used? Does anyone know where to find a cheap kit? Im going for a sleeper with this project.

The motor currently has 340 heads, performer rpm intake, 650 cfm Edel carb, and mopar nostalgic cam with .484 lift and .284 duration (advertised). I don't know anything about the bottom end or the numbers on the heads because this is how the motor came when I bought this car.

Ideally, If I went with the 318/390, I'd like to be able to use the parts I have now. Will the 340 heads flow enough? And would a different cam be better? Im looking for 400+ hp with good torque. Thanks for all yalls input.
