need better 60 ft time

I have the same problem, running mid 12's at 111 mph with a crummy 2.0 60 ft time. Car is not spinning or bogging off the line, just lazy out of the hole.

Everyone has told me to go with more converter. I've called around a few converter shops and they have all recommended 3200-3800 RPM range stall speed in a 10" converter based on my engine/car specs that I provided them.

I'm currently running a 2000-2200 RPM stall right now similar to yours.

I'd go with what the above guys said, more converter should help you out. From my understanding, getting a good quality one will still have good street manners without too much slippage and heat vs a cheaper one that stalls the same RPM but slips a lot around town and generates a lot of heat.

I'm thinking of getting one next year. If you get one this year and run your car again I'd be interested to see how much quicker you go. Keep us posted.

With 115 mph trap speed you should get into the 11's no problem with a higher stall speed converter.

I've heard of guys using 4000+ stalls on the street with no issues. As long as you run a good trans cooler and its a good quality converter, it shouldnt slip much on the street.

My car is 95% street and I told this to all the converter shops and they all recommended 3200-3800 RPM for the street. They said it wouldnt slip much more than a stock converter on the street, but when you punch it, it'll spin up to the stall RPM and take off.

From what I understand its based on your engine's peak torque, your cam, car weight, rear gears, and several other factors. The idea is to get the car right up to peak torque off idle and keep it there until the gears keep the RPM's up once you're rolling.

It sounds pretty aggressive, but I've heard lots of guys rave about their 3500 stall on the street and they have no trans issues at all.

There seems to be a big difference from a cheap off the shelf unit vs a custom built unit. The smaller diameter, the more efficient the unit is as well. All the shops I talked to said a 10" converter would be fine on the street for my car. But you should try giving a few converter shops a call, fill out their online spec sheets and submit them, and they'll get back to you with what they think is best. Then you'll get a better idea too.

This is just all what I've heard or been told by guys on the forum here. I'm sure they can give you a better idea of what to look for and what the difference is between various converters.
