Look here at the HP/TQ curves for both engines:

If you download the images you can actually see the text quite well. I was trying to superimpose one image on top of the other but could not do it. Lots of power curves out there from dyno runs on modified engines, but can't seem to find any stock for either engine except for these?
Anyways, up to about 3,000 RPM, the numbers are somewhat close: maybe around 150 Hp for TBI and 190 Hp for Vortec. Well, maybe not that close? Beyond that, the Vortec has an edge. I think that's consistent to what I hear about the TBIs not making (much) more power as they rev more. But I don't know as I have not driven one, well at least not in the same exact truck configuration as the Vortec. Torque numbers are "close enough."
