Build 400HP 318

You can almost stumble through the Summit book and get that kinda HP from a 318. Get a piston that yields a blueprinted 9.5 to 1 using the 340/360 LA heads. Have some mild bowl and port work done...and a good gasket match. Stick with the 1.88 intake valve. Get a GOOD brand 1 3/4" primary tube header. Talk to hughes about a camshaft. Run the Edelbrock Air Gap intake with an adapter plate and a Thermoquad. You'll be bumpin or a hair over 400 HP.
