LSX376 intake?

[jknox67]

I just bought a gm performance lsx376. I have an intake from a 5.3l engine with injectors and whole wiring harness. Will this intake work on my new 376 or will I have to buy a new one? Any help would be great.

LSX376 have LS3 style heads. Big "square" port style versus the old style tall skinny cathedral port of previous LS motors and your 5.3 current engines. You will need a new intake.
