S300 or s330 in my compound build poll

[SuperiorRam]

Ok I've been debating with myself for too long, so the question goes out to you all

I have a s330 race cover 62/73/14 and a fmw 64/68/14 one has hx-40 outlet the other 3rd gen (otherwise I'd just switch back and forth)

Going over a cast eight blade s480/96/1.32 with some narly side by side piping I only want to build once for my conversion toy truck.
It's a 89 lower end (big bowl) 5x.018 sticks Seth's 215 putting out 525cc's about 28.5* timing
I'm thinking the 73 turbine wheel on the 330 will make me the happiest as I had the same charger on my cr with a billet 75/96/1.10 and loved the spool (1800 ish).
Right now it's running a e.d billet 72/74/.90 and the truck only weighs 4000 lbs so faster spool is what I'm after, making me thirst for the 86 turbine. See my dilemma?
Any input is appreciated

Get the 351 outlet turned down a touch to the hx40 side and try it both ways.

I also have a .91 housing for the 68 wheel and have been debating a .91 for the 73
Help I'm going insane. I want to get this build done before the snow flies. Ick

Go with the68 turbine then you should be fine.
Though I would still machine the outlet down, makes parts cheaper
