Can anyone confirm that the Holley 534-209 fuel rail will fit a stock LS3 intake?

Also, will my Injector Dynamics 1050x injectors fit OK?

Lastly, will the fuel rail take -8an fittings?

Is that higher flowing than the one i posted? I will be running around 800-900rwhp and twin turbos.

ID offer the injectors in various fitments with various adaptors....so you'd need to know exactly which fitment you have to stand any change of knowing if the rails might work.

Although I' sure they can easily be adapted one way or another.

Holleys spec clearly states the rails are tapped for -8 fittings. "Fuel rails are machined to accept -8 (3/4-16) O-ring fittings"

5/8" would easily support 2k+ and then some.
