Re: 540 Engine build-up.

I would go with a good 4150 series Holley. The 4500 stuff is to big. You'll never need that much air with a 540 in front of an I/O drive.

Dart / Merlin make the intake with brass insert its a good choice as someone already mentioned for salt water

I like this theory. I agree running the rectangular port manifold would most likely be my best choice.

Thanks for all the replies..
