Default Re: Intake manifolds

A quote from BigBlockV6;
Quote:
Just remember that the V12 has different intake manifolds due to spacing and they will not interchange with the V6

(question asked)
That is an issue with the magnum heads. Correct?

No That is an issue regardless of heads You simply can't use V6 intake manifolds on the V12 nor can you use V12 intake manifolds on the V6.
Other than the above, my understanding is that they interchange.

I changed out my One barrel intake for a two barrel and did the Holley upgrade.

Now another member, TJ, put a magnum manifold onto his non-magnum 305, with a four barrel carb and it runs fine.
