How streetable are the 4000+ converters?
How streetable are the 4000+ converters? Curious how loose these big converters are? Do you guys drive with these converters daily? What is a good gear to run with these converters?
the only way to truely understand is to ride in a car with similar gearing, torque, and convertor size that you want. its all relative. i consider a 4K convertor i run 100% streetable. some think it is crazy. daily driveable....thats just what you are willing to put up with.

I drive my car with a 4200 converter every day. Some people might not want to...but it doesn't bother me. Your best way to tell...find somebody near you with a converter. Ideal would be someone with similar mods and size converter that you're thinking of.

I'm assuming your talking about a bolt-on car with stock internals. I would say a good gear to help tighten things up a bit is 3.73's. 4000 stall's tend to come with pretty high STR's so street driving becomes real tricky due to traction or lack thereof.
3000-3200 is super street friendly and you'll hardly notice anything different until you punch it.
3400-3600 is street friendly and the most popular stall size for stock motors and daily drivers. You'll feel a little looseness and it'll take a few weeks to get used to, but then it'll feel stock.
3800-4000 is streetable to some and too much for others. This is where people decide what they can and can not stand as far as stoplight to stoplight driving.
If you stay with stock gears then go with a 3500 stall. If you upgrade to 3.73's then a 3800 or 4000 stall with a 2.7 STR should feel pretty good if you don't mind a little looseness.
Hope this helps and good luck

4200 here. I don't mind it at all. With the 2.73's it's a little loose but you get used to it pretty quick. It feels great with 3.42's and 3.73's. I've driven with mine for the past 40,000+ miles.
Some might think it's a little much, but one trip to the track and I didn't mind it being loose at all.

I daily drive a YPT4000 with 3.42s. Relative to the Vig3200, which I thought was very streetable, the Yank doesn't feel that much looser. It makes the exhaust sound louder and I get about 11mpg in town now. Those are the only complaints.

Hey gator do you ever play on the interstates late at night????
I think that was you
I just switched from a PY3400 to a PT4000 in my mostly stock (lid, LS6 intake, 3.42 geared 12 bolt and Loudmouth exhaust) 2000 SS. I switched because I'm planning on playing with the car N/A for a little while instead of going straight to a turbo. The PY3400 was perfectly streetable and worked pretty good at the track too. The PT4000 is a tad loose on the street for my taste but that's strictly a subjective observation. I haven't made it back to the track to see how much of an improvement I got from switching but I think I'm going to need sticky tires to get the full benefit of the PT4000. It hits the tires really hard and now traction is a problem in both low and 2nd gear. Once the converter locks up, it's exactly the same for driving down the highway. Maybe I need to get used to the way the PT4000 drives as I just got the converter changed.

When I say it's loose...basically how much pedal you need to get the car moving. Obviously when you floor it the RPM's will go way up. It's normal driving that people are worried about. The STR will afect how loose the converter is.....along with the gear ratio. The difference between the 2.73's and 3.73's was night and day for me.

OK. Can someone point me in the direction of a manual or something that explains the stall numbers? What does 3800 stall mean? What does "it feels a little loose" mean? ( ok, now I kinda know what loose is.. )
Just trying to get all my stuff down so when I buy a tc I don't buy the wrong one or something that's gunna eat through tires like crazy. ( 3.23 gears )
