last,
According to the Edelbrock site here:
Intake Manifolds - Ford - Big-Block - Torker II Series - Edelbrock, LLC.
the lowest manifold they make is the Torker II, and it
Their quoted port size is 1.75" x 2.1". If you decide to use it you can do a port match - I think I recall there's enough material there for doing that.
I use this manifold and its EFI twin on two 385s, each much larger than 460 and they run just fine!
Hope this helps,
Tom
