It's a 5.3 I opened up the top ring to 28
Patriot ls6 heads
Ls1 intake
Gt45 turbo
Twin walbro 225 pumps
8an feul line
Stock feul rails for now
Heads studs ls9 head gaskets
I want to make around 650-750 hp to rear wheels
I have a level 5. 4l65e tranny with a fti 4200 stall and 4.11 gears

If you keep that stall, consider dropping the rear gear to 3.23 or 2.73, otherwise you'll be blowing through your gears faster than you can build boost.
Are you running 1/4 or 1/8th mile track?

Definitely drop down to 3.23s, regardless. I'd like to see what it would do with the 4200 stall and 3.23s. Jumping right into the power band would help launch (in theory), and the 3.23 gears will help load the turbo and let you wind out gears. If you have the time, maybe put it together with the 4200 and see what it does (with the 3.23s) before you send it back to be re-stalled. If they're going to do a straight swap (and it has to be unused) then just send back and get the 3200.

I'll sell you mine! I'm looking for a custom grind for my convertible.
I'm very likely going with: 228/234 .588/.598 on 114 LSA
I put one (228/234) in my 4.8 build (in progress). It will hopefully spool the turbo up fast, once I get the car back from my body guy and the engine put in. Waiting.... waiting... waiting... uggh.
You might hit up Martin Tick Performance. He's pretty reputable for spec'ing cams and could either spec a custom one or has one off his shelf that will work good for you.
