Motochris,
You never said if your vortecs were modified for more than 0.450" valve lift.
If they have you may want to consider a Comp Cams 270HR roller cam with 218* duration @0.050" lift single pattern, w/.500" valve lift w/1.5:1 ratio rockers. Using Comp's Camquest software with your engine specs it indicates 404HP, and 463ftlbs of torque. You can get a few more rpm with the XR270HR to get 411HP and the same 463ftlbs with a slight loss of torque off idle.
Both should work good with your torque converter IMO. You may want to upgrade your valve springs.
FWIW,
ssmonty
