I'm building a 440 to go in my duster. Its a 77 HP block with a earlier year steel crank not sure what year and six pack rods I believe. Its .030 over with sealed power pistons not sure what type but they have a slight dome, my valves barely clear thank goodness for thicker gaskets. A voodoo 600 lift solid roller cam, crane roller lifters, harland sharp roller rockers 1.5, ported, polished, and angled decked 906 heads with 2.14 and 1.81 valves they are practically closed chambered, a team g intake with a spacer and 1000 cfm demon. I don't know the compression ratio. I was wondering what kind power it would make any help would be greatly appreciated . Thanks
