TorqStorm Supercharger build advice needed

Well, quick math says 4.56's w/35's~=3.82's w/29's, with a curb weight~3900#. IF He's not pulling a trailer, IF He doesn't decide He wants more & tosses a smaller pulley on the compressor, IF He doesn't stray far from Home & get a load of bad fuel, IF IF IF..... I'd still use forged slugs starting from scratch...
I agree! All those "IFS" are also why I suggested the lower compression.
