What size injectors should I use? Building Street/Strip car - not a daily driver; Goal is 450-475 RWHP (want to see 11's soon!)
Car is 1995 Z/28 so complete conversion is required from LT1 setup.
Currently stock 460LE, likely go M6 after build w/4:10 rear.
Purchased Factory "Still in the Crate" LS6 long block.
Purchased the Thunder Racing RAPTOR cam (236/242 615-617 lift both sides - 111 + 2 degrees)
PurchasedFAST 102 mm intake & FAST 102 big mouth throttle body & billet fuel rails.
Next Purchase Trick Flow 215 cc Heads (will purchase in next two weeks!)
Also looking for a good set of lightly used Kooks long-tube headers.
Questions: #1. What size fuel injectors will work best with this combo?
#2. Which aftermarket MAF would work best with this combo?
Car has BMR suspension setup,AGX shocks, Z06 Rims and carbon fiber SS style hood. Should be pretty intense when complete!

Factory LS6 injectors (28.8) are good to ~420whp. Probably want 32 lbers to be safe. Always good to run an injector as close to 85% duty cycle as possible for optimal spray pattern

Grab some 36 or 37# injectors to give yourself some "wiggle room" there.
