  • 3.1 intake manifold help

    What are the different intake manifolds i can put in place of the 31 intake manifold, do i need to change the heads or can i just change the upper and lower manifolds?

      2.8 and 3.1 intakes are the only bolt ons for that application. The 3100 ports are much closer to the 3400 ports.

      You'll gain much more by swapping to genIII heads and exhaust manifolds anyway.

        You'll need more than just swapping parts. Custom pushrods, extending wiring, changing throttle cables, threading for ect, maybe custom engine mounts... You know the usual stuff.
