318 hp estiimate??? need input

I recently got a 318 .40 over smoking it's butt off I bieleve the oil rings are shot because it has good compression anyway. I am honing it out new rings and I took the 302 heads and ported and polished the intake and exhaust sides and port matched them I am also running and comp cam 260h cam with possibly a 65 model 273 commando intake also ported to 360 size and, drilled to fit new bolt holes. Can anyone guess about what this will make also with a 260 duration .440 lift will It have any noticeable lope? Also any suggestions or camshafts for sale? Or any parts really?

Thanks, Kevin
