Your 408 will be more stout than mine as I have Eddie RPM heads. 251/255@050 cam. 4.10 gear with 28" slick. Unported Super Victor intake which everyone here says is not that great.
Car runs 11.teens @118. 5000 stall from an 8" ATI TreeMaster TC. I hold it at 1900-2000 rpm to stage it then mash the pedal and hang on!!
Drives on the street like any other torque converter - have to keep your foot on the brake at idle (1000 rpm), no "mushy" feeling, etc, etc. You would never know it is a high stall converter. Trans temp typically in the 160-170F range when driving on the street. At the track, it leaves the line around 150-160 and hits 180 at the end of the track. By the time I get back to my pit, temp is typically back down around 150-160.
