What stall torque converter do I run?

3.27? You must be runnin a Ford 8.8.

BEFORE you spend money on a big purchase like a converter, make sure your combo is in the best tune for what you have NOW. Can you describe to us what "bog down" means? In other words, HOW MUCH of an RPM drop? 150? 500? If it's a lot, you may have some tuning issues that a new converter will not address.
