Hello, our 46' Roamer Riviera has the original CC 427s in her. They are tired and I'm tired of vintage engines. I'm considering repowering with 454s. There are not many complete turn-key sources. One shop that will build a pair for me is Daddy-O's Marine in Pompano Beach. Anyone have experience with these folks? Some reviews on other forums are not too good. Another option are the Marine Power builds-pricey but complete and they have a 2-year warranty. My concern is we'd be tearing them down to almost a short block to get them through the door and down the stairs (I am NOT cutting the roof out). Which leads to the other option; buy a pair of reman long blocks from First Mate and acquire the rest of the components to mimic a Crusader. Looks like I can get most of the stuff from MarinePartsSource, but it might get pricey. Thoughts?
