454 Manifold Upgrade?

Has anyone upgraded their factory TBI manifold to a 4bbl manifold? I am looking to do a EZ EFI FAST upgrade to my 92 C3500's 7.4 454 and want to swap out the cast iron boat anchor.

Anyone upgrade their manifold?

Yep.

I have the Eldebrock BBC manifold.
Easy just bolt on. Using the factory throttle body/

Big difference in mid range, it is worth changing out.

I did a good mid range cam also. Now its not a slug like the factory setup.

Whats the part number? Is it a 4bbl or TBI manifold?

454 TBI manifold.
I don't see any part numbers.
Been on the motor for 10-15 years.

Looking for 4BBL.....4 Barrel Carb, not TBI.....
