Guess the HP!

Hope I'm not hijacking the thread but what would this same combo do with Trick Flow 270 (MW port) heads, similar cam but only about 9.5:1 compression? I have a 440 I started building originally as a tow rig engine but put it on hold and decided to change direction while still using the short block components I already have (factory forged crank, 440Source replacement rods, Icon 9947 FHR pistons).
