402 ls2
Heads/cam
Th400
12bolt. 3.73 gear
Weighs around 3,000
Will be getting anywhere from a 150-250 shot
Keep getting mixed opinions on all sorts of converters.
.. Yank 3600 or 3800...FTI 4000...Ptc 3600.. etc... What u guys think ?
Car will be street driven, but nothing crazy or far rides.

I have a very similar combo as the ones ya'll are asking about. I am running an FTI 3800 billet triple disc nitrous spec converter in my 4L85E tranny and 12 bolt with 4.11 gears and 28" tall tires. The nitrous spec converter is a little too tight for a optimized motor pass, but is very efficient and drives very well on the street and works very well with the 150 shot so far. On a motor pass I go through the traps around 6350-6400 rpms @ 123-124 mph. On my 150 shot the 4.11s are too much gear, I am on my 6800 rev limiter approx. 75 ft before the finish line in the 1/4 mile. Going through the traps @ 6800 rpms I was trapping 131.6 mph, which is just shy of what I think I need for a high 9 sec pass. I'm gonna put in some 3.73s that I have waiting on the shelf.
I just got finished ordering my next mods, Strange lightweight spool and Richmond Gear install kit. Going with the spool to insure equal traction at both wheels on the juice. The 3.73s should let me make an all out full pass on the juice.
