318 2bbl manifold swap with OE cam - worth it?

I'm going to be doing the same to my Dart until my 408 is done, I just wanna drive it. I have a 318 lying here, bearings look good, bores look good. I also have a crane .460.450 224/232 cam, new valvesprings, timing set, and 1850 Holley 600, manifolds, and 2 Flowmaster 50 series mufflers. All I have to do is find a LD4B, get gaskets and an oil pump, and I'm going to see what it will do. Oh, and I'm gonna port the 318 heads a little. I won't barely have any money in it, everything but the valvesprings and timing set are used. The trans is a 904 that I just rebuilt with a converter that stalled at 3200 with my 360, I'm guessing it will be lower now but it has to be better than stock. The rear will be 3.55 sure-grip 8 3/4, SS springs, etc. Any guesses as to what it will run? My LD340/same cam/home ported stock valved J heads on a stock bottom end 360 ran 13.60's for the last 10 years, and I barely ever ran it easy. Still ran good when I sold it, and that was with a peg leg 3.23 center.
