I have a 57 classic plus in the bridge of my strat and it definitely bites. Doesn't sound exactly like an LP, but depending on what you play, it can do the job. If you want the best overall sound, you can try a 500k tone knob and use only the bridge pickup with it. Another option is the use an HSH or HH Stratocaster. I have an HSH with a Sh-1n in the neck, custom middle and a 57 classic + in the bridge with 500k pots. It's much closer to gibson than with the 250k stock pots. The neck sounds very "straty", a bit thicker and it's definitely killer when the distortion is raised up.
