Re: few question about 4.7 wk
I think what Swede is saying is, you've got almost 5000 lbs. (without you in it) of iron you're hauling around, and it would take a ton of $$$ to make it move repectfully. Over the past (almost) 4 years, I've sunk ~$4000 in mine with a 5.7 and, while it's much better than stock, it's still doesn't set the world on fire....but it is much more fun to drive. Now, if you go get an early model SRT-8 (stock they're faster/lighter than the newer ones) and sink an additional $20K or so into it, you can have a 10 second quarter mile ride. Just isn't worth it, IMO, especially if it's a daily driver like mine.
