I am trying to swap intake manifolds on my 318 to a 340 manifold so I can go 4-barrel. However, now that I have taken most of the bolts off I have come to the conclusion that the water pump is in the way which is bolted to everything in its general visinity.

Can anyone tell me the quickest and easiest way to swap manifolds as well as what all I need to think about replacing as I go?

I am also swapping ignitions but I got a guy helping me with that in a few days. Just thought I'd go ahead and get the intake swapped out before he plays with the ignition that way we don't have to worry with it.
