The auto hi performance sources have marine products as well. Try
summit and jegs. If what you want is really more torque at low rpm's
you may have to be satisfied with what you have. Most factory cans do
pretty well in that regard. Aftermarket cams tend to develop more
power at higher rpm's. In any case to get the most bang you probably
need cam, carb, and exhaust. Once you start down that path at some
point you'll start wanting a pair of 502's :-)

I would like to get a little more torque out of a pair of 454's

A 454 is a 454 so I suppose a heftier automotive race
cam would provide you more torgue, but you have to
account for changes in timing, fuel delivery and such
to really make it work properly. It might not be all
that advantageous in terms of time and money.

I would think a prop change would be of more benefit
for those engines than a cam change.

Why do you need the extra power?

Come to think of it, you'd also need to change props
anyway - I'd try the props first.
