the drivability is going to be much better with the 3.0 due to the higher torque multiplication however its going to be less efficient at getting the power to the ground at higher rpms compared to the 2.0


and fwiw there isnt a converter yank advertises thats going to stall above 4000rpm behind a stock head/cam ls.

the PT converters advertised as head/cam converters, they will stall 400rpm lower behind a stock head/cam motor.
PT4000 = 3600
PT4400 = 4000

the PTs have a lower STR but are more efficient on the top end.

its important to match your gears/tiresize and converter together. i think alot of the reason people bitch about big converters is because they put 3600+ converters in cars with 2.73s, 3.23s and 3.42s, more load = more work.
if your going to run those gears go with an SS converter, youll need the extra torque multiplication your loosing with the stock gears.

Thats good info right there. At first I was pretty much set on a ss3600 but I really wanted a converter that would pull like a sob up top as well. Thats why I was thingking PT4000. But the decision is tough cause its mostly a street car. I wanna be able to mess around with other cars stop light to stop light. From all the research Iv done iv learned you cant have the best of both worlds in a converter.
