400 horsepower low compression 360

I want a 400 hp 360 built for my 64 valiant. Here is what i currently have for parts, which i would like to use.
75 block with factory pistons
Edelbrock 750 carb
Dougs headers
Factory 68-69 cast intake or torker 340 intake
Factory ignition
I am open to opinions, tips, and advice on head and cam selection
Can this goal be achieved with factory dished pistons?
Thank you
A 75 360 should have a 9:1 compression ratio. Closed chambered heads and a reasonable head gasket should get you to 9.5:1 or better.
