4000 stall help Ok, well im still deciding which converter i would like to buy, so i have a few questions.
Would you hesitate at all to buy a used converter? I found a pretty good deal on a used Yank PT4000.
Is a 4000 stall going to be to much for a street driven (on occasions) roll racing bolt on ls1 (will be cammed in the future)?
Also, the 4l60e has 118k on it now, will it be able to survive a new converter with that many miles on it (already has a tranny cooler)
Thanks tech!

Not the most knowledgeable but with your mods that seems a little extreme. I know my C5 with the basic bolt on's and a 3200 stall feels a little laggy around town but launches very hard. Since I don't launch from light to light or when out for dinner or heading to work, it sucks monkey ***** for me. Drive a friends car with a stall and see if it is your cup of tea.
I bought a used Yank without much worry, I think it costs $250 or so to send it in to be repaired if need be...but if it's full of trash from someone's build gone bad it could ruin a transmission quick
PT4000 should be a good roll race converter if what I remember reading is correct, but may or may not feel too loose to you depending on personal preference
It will work both stock internals and with a good size cam
There is no way to know how much longer the trans will last

You should also take into consideration your gear ratio. I love my 4000/3.73 combo. Its still slightly lose, but not bad plus Im also used to it now. A 3.23 or lower with a 4000 means your going to rev the **** out of it while city driving, and might feel really laggy while just cruising. Either way...go for it, you love the performance difference comparably to your current setup.

You will probably like the 4000 better after the cam swap, especially if you go fairly big on the cam. With the stock cam, the converter will feel looser because the stock cam makes more torque down low. With the big cam, the torque will come in later, so the converter will feel tighter till you nail it and the converter flashes. Be careful about buying a used converter. Get it cleaned out before you throw it in front of your trans, or the rebuild may come much sooner. Good luck!
