390's for the water

P,
I think a pair of 390's would work fine in your application if you used good machining and good quality components. For example, a .020" overbored 390 with flat top pistons, Edelbrock Performer RPM heads, cam, intake and carbs. Good quality roller rocker setup from Harland Sharp or Erson. In other words no medium quality parts, only best quality parts. The 390's built like this would be powerful and reliable with power equal to or maybe better than your current engines. The crank and rods in any 1967 - up 390 are identical to your 427's so that would not be an issue. Forged pistons and a good balance job would be recommended. The Edelbrock heads have bronze valve guides and hardened valve seats so longevity would be excellent with unleaded gas. For your RPM levels the Performer cam might be a better choice than the RPM.

That's my take on it.
