It is basically the same as the 350-400, only with a over drive, was used prior to the 700.
The question of the topic should have been what is the best late model trans..
Best bet for this guy is a 4l80 with a shift kit, takes alot of hp to break.. The 6-=65s are great in rcsb trucks, with hp, but not for ccsb or ecsb trucks, weight kills them..

Why don't you call Vince and ask him? I have an FLT Stage 4 with Vig 3400 and Sonnax on 1-2 and 3-4... not a problem one. And I'm running with TruTrac and Yukon 4.10's....

You will have to mod the trans member, get the drive shaft shortened, get a wire harness to adapt to the old one... With that hp a lvl 5 should hold that power

if yer talking about 60e thats why they broke even the lvl 5 60e isnt designed for that much power with the weight of an ECSB, those 60es really arent meant for powerful trucks period...now break a FLT lvl5 and your doing something serious..but a lvl 5 60e. i wouldnt run even 500hp with on a RCSB
