Slant 6 engines

I have been asked to come up with a streetable combination for the slant 6 engine and run on pump gas, so this is what I've come up with.
engine:225
compression:8.14
valves: int.1.70-exh.1.44
intake:Production 2bbl 250cfms
exhaust:hedders 1 1/2 44" long with 2.25 turbo mufflers full exhaust
Camshaft: mopar p4120243 .436 lift 244 adv. duration valve lash int. .010/exh. .020
Octane:93

peak HP: 120 @ 4000rpms
Ave. HP: 79.5
Peak torque: 192 @ 2500 rpms
Ave. torque: 139 ft. lbs.

These little engines are going to have the hardest time makeing power as the factory rated them @ 100-105 stock so the gains won't be much as by the looks of things but they are substantial to a small engine.
There are other things that can be done and make more power but they won't run efficently on pump gas.
