Default Suggestions for my upcoming build?

So I am ditching my N2O this winter and going turbo. Here's my plan so far...
Stock internal motor
228r cam (it's already in)
317 Heads (gotta sell my TEAs.)
".040 Headgaskets
Truck mani kit, hotside/coldside fabbed by a local shop
Precision 76mm turbo
Griffin Radiator
Notch the stock K member
Meth injection

Now here's my questions...
I have a walbro 255 FP in the car right now, am I going to need another fuel pump? How should I set up my fuel system?
What size wastegate should I go with, any brand recommendations?
BOV?? No idea what to get.
Injector size?
I am shooting for 650 on pump/meth, rev limiter set at 6400 RPMs.
What PN for the Griffin Rad?
What fans should I get to move the air through the rad?
Oh, and the car will be getting an SD tune.
What else am I forgetting? Thanks for the help guys.

2 of the 255's will be able to fuel whatever u can get outta the stock internals and then some. ur good on fuel.

if you want to have a setup u can have peace of mind, and be able to up your HP in the future, run a -8 feed and use stock line as a return.

60mm jgs wastegate(u will need a big gate to get down to the low boost required for stock internals)

tial BOV

80# injectors



what "stock internals" is it?? ls1? lq9?

Sorry, it's a stock internal LS1. Forgot to mention that
Should I just run the dual 255s straight out or should I hook it up to a hobbes switch to activate on boost?
Thanks for the advice on the big gate, I think it'll only need 8-10 lbs to get it to where it needs to be...

Haha, thanks for the bump! If no one answers, I'm sure I'll be able to work it all out on my own. Lots of turbo LS guys local to me.

No need for 80#s unless you plan on going e85 with significant amounts of boost

I have 60s with plenty of injector left.

Hayden fans do the job.

I was figuring 60s as well. I'm only gonna be on like 10ish lbs (still double what you're running homo).

I still need to come by and take measurements off your pile so I know how far to cut and ****. Call me.
