Best bang for the buck?

I think my biggest piece of advice here will be when you DO get ready to spend money, don't be scared of a converter. Converter technology is fantastic these days. You can get a converter tight enough for street duty with pretty much zero extra slippage, but will flash to 5K if that's what you want. I agree with fishmens67 too, that a converter that will flash around 3500 would be very good......that is WHEN you're ready to get there. And hell, don't let us decide that for you. Order the thing tomorrow if you want to. lol One last thing. Don't skimp on the converter, get a good one. I recommend Precision of New Hampton. Great company and very reasonable. Call them. Tell them what you have and what you want. They will fix you up. Like @crackedback always says, on an automatic car, the converter is the single most important piece in the equation, bar none. So get a good one.
