Re: any benefit to ported TB + TBS?
Wonder why yours is so much lighter than the 5.7 ones? Are you 4WD, with all the bells and whistles, or pretty much bare bones? I don't think there is that much difference in the engine weights. Mine weighs about 4800 lbs. I'd love it if mine weighed only 4200 lbs. That's about what my Hemi LX weighs....4260 lbs.
Bet the headers made a big difference on yours too. I know when I had my headers built, it was like sticking another, more powerful engine in it. Big difference.
