VB upgrade and a high stall TQ converter, together should run about 1000 Americans, so you get longer transmission life and a faster car.
No one knows where the stock auto will crap out. I'd venture to say 350 with a good transmission cooler and decent fluid.
You can run 15 lbs on stock internals. 350 WHP has been done with no problems. A stall converter will be very harsh on the transmission, it doesn nothing but superheat the fluid. I'm not saying not to get one. They work great, but don't be mislead to think they help for strength.
I loved my auto Skyline, friggin blast to drive.
