    Edelbrock Performer RPM question

    Anyone have any experience with the Edelbrock kits? I have a 1997 7.4L rebuilt merc motor in my SeaRay 230. I had the engine rebuilt to stock specs thinking that 330ish HP would be enough for me, but of course now I'm wanting more power and performance. I already have a Edelbrock 750 carb and...

    Mercruiser or standard automotive oil pump?

    I've got a rebuilt 7.4L engine from US Engines that I'm going to drop in my boat, but I was told that I should get a new oil pump for the new engine.
