well for who know i did the 6l90 swap on my 08 rcsb 2wd 6.0,h,c,i 480 rwhp with 410s out back with a yank 3600 ,the issue im having is the truck will only brake stall 2400-2600 and my best 60ft is 1,79 ish and still managed 12.53 at 109.5 testerday at famoso, so i wanna change converters and ive been thinking of a 4400 and since im in the process of putting a 125 shot i dont know if i need like a multi disc or somthing. so expierience in this setup would help

 

What are the specs on that cam?

 

230-236 590 ish 600 ish lift112 lsa dont remember the exact lift its been awhile

 

You definately need more converter. 4400-4600 ish should work alot better for you.

 

yup thats what im thinking especially since the 6l90 first gear is so steap then the 411s out back make that gear alot steaper so u need more converter to brake stall higher

 

Spray is a shot to the drivetrain. Get a lockable converter imho

 

What does it flash too?

 

You will definitly like the 4400. I went from 3200 to a 4400 and it made a huge difference. Dropped the 60ft from 1.85 to 1.70 i think it still has more in it. My cam is a 232/234 598 lft 112 lsa in my ls1

 

i really dont know what it flashes but it feels like it needs bigger but i think yank sells a 4400 nitrous converter
