Each to his own I guess..I've been pulling heavily loaded trailers (6-8000 lb) for over 30yrs..I've gone thru my fair share of smallblocks..I've never owned a smallblock that can hold a candle to my LS..a bigblock or diesel is a different story in torque... but this is smallblock vs LS.
I'll take my LS any day over a smallblock.
as far as a downshifting LS goes you have to consider these newer trans have a multitude of gears in them (my newest truck has 6) so yes a auto is going to be more inclined to hunt a lower gear..my tow rigs have been mostly manual trans though so I pick when I want a downshift..
