Budget build on the cheap

Here is what I have lying around that I am just going to slap together....


82' 360 block, stock bore
stock stroke cast crank
9:1 flat top pistons
stock connecting rods
stock 340 cam
stock heads
edelbrock LD340 intake
holley 550
flowtech 1 5/8 headers
stock ignition

Clearly not a well thought out build but this is lying around and free. how much more power than a 318 2barrel should I expect?
