I'm Awesome
The LT1 cam makes more low-speed torque than many aftermarket cams. I went from a flat tappet MTC1 204/214 to the LT4 roller cam years ago on a L05 and the stock LT4 cam killed the MTC1 everywhere. The 8800 is a great cam, but it does have more overlap than the LT4 or LT1 cam. We also had a 1996 LT1 cam in a L31 in my brothers 99 Suburban. It would move that suburban along in overdrive with the TCC locked at 1,200 rpm @ 40 mph effortlessly. The LT1 cam has a table top flat torque curve. The 6492 cam I have in the 1987 G20 is on a 115.5 LSA. It has great off-idle torque as well. At 10.25:1 it cranks at ~195 psi compression. Even with the TH400, the stock ~1,800-2,000 rpm converter that came behind the L03 305 that stalls 2,500+ behind the 350, and a 3.08 gear it runs strong.
