For a 1.9liter blower I don't think you should be disapointed with 720rwhp and a MONSTER 772 torque reading. That blower is little on a 6.2 LS. You are asking it feed a bigger engine - It is just maxed out at this point.
Also you shouldn't be afraid to build a higher compression stroker. 8.3:1 is low. When I put a forged rotating assembly in it will 10.3-10.5:1 and will run 13-15lbs out of a YSi.
