Sounds like a good plan,
The only possible issue I see is without correcting your tire size/speedometer with a tuner,
you may hit the governor (105mph) before the end of the quarter and fall on your face well short of the traps.
at about the 1000' mark you'll be moving around 90 MPH, but your speedo will register 105 mph and the governor will retard your the throttle.
(about 10% smaller tire = speedo reading about 10% too fast)
I have a similar list of mods on my 10' RCSB 4x4 (about 300 pounds heavier than a 2wd rcsb)
and get 13.8's @98 MPH, 60' times are 1.8's (with a tune) but only an open diff with shitty 3.55's, DA here is usually over 2500'
only weight reduction was the spare removed. (tailgate and bakflip tonneau still on)
I run M/T 295/45R17 ET Street DR's on all 4 corners and often use 4WD auto for a full throttle launch since I added the Street Edge 2800 stall TC.
in ideal conditions with good track prep, a fresh layer of traction promoter I can still hook in 2WD.
Total weight for tire and wheel combo(17"x9" Moto Metal alum wheel) = around 60lbs ea.
that's about 30 pounds lighter than my 305/50 Terra Grappler's on stock 20's I use for the street.
(truck is a half second slower on my street tires) effective gear ratio goes from 3.55 to 4.30:1 when I swap to my M/T's
Tires measure about 11" wide x 27" tall mounted. DOT legal so I can swap them at home and drive them to the track.
If I had a rear locker or limited slip and 4.10's I bet I could hit 1.7's for a 60 footer in 2WD. current best 60' is 1.870
