Default .96 or 1.15 a/r housing behind 355 LT1?

Long story short
I have purchased a log kit from real quick like 2-3 yrs ago one of his 1st. This one came off of 10sec lt1.... Anyways lost interest in this for a good while, the other day I was figuring how much $$$ i have in this pit, which made me decided to go ahead and get the thing going. Yes throw more money at it

To the point:

Which exhaust housing would be better for this kit/build the .96 or the 1.15 twin scroll. I am thinking the 1.15 as it will flow more up top and spool almost identical to the .96 housing. Any insight on this would be appreciated...

Specs
3.480" 4340 crank
5.7" 4340 h-beam rods
-24cc dished diamond pistons
Custom A.I. Turbo Cam
Splayed Mains
1/2 filled
Off the self 62cc TrickFlow Heads
1.6 CC Ultra
TH400 Trans
Stall?

Looks like a pretty knarley short block..but i would start with a hp number or a time you want to run then start looking at which turbo to run..I would think the .96 could get you to 800+rwhp, anything more i would step it up to the larger.

Depends on the unit. The 76GTS the biggest you can go is .96A/R so no choice other then that. If its the Tnetics unit with the F1-68 wheel, then definitely go with the 1.15A/R...as its almost identical spool to a .96A/R and you get the added flow with the smaller turbine.

TC76 F-1 GTK Turbine wheel. Hoping to run it at 14/15 lbs no low/high boost setting. I want it to run top notch all the time no excuses. no low boost setting or anything like that, its a weekend car so it will come out and play weather permitting.

That will work just fine with an LT1 and a 1.15A/R. The LT1 doesn't have the heads of the LS based motors so it will run just fine with that setup at that boost level.

DrTurbo how much is the 1.15 housing for the TC76. Is it taller or a bigger diameter at all? My setup sits tight to the crank pulley with the .96 A/R. How much more potential does the 1.15 have over the .96, is it even worth swapping?

The 1.15A/R is around 1/4" larger Diameter.
