Thread: 455 olds question

  1. #1
    darren
    I just bought a Bojo boat, anyone ever heard of them?? well anyways I need some advice here. I have a 455 oldsmobile engine with a lot of Hardin Marine stuff on it. someone spent some money making it look pretty. The problem that I found when it ran rough is that the block is cracked. I am going to need a new block I really want to get this boat on the water, because thats where it belongs. My question is sould I scrap the whole idea of putting a 455 olds back in it, as I have ran into serious dificulty obtaining one. Or should i swap it out for a 454 where parts are a little more easier to find? What to do, what to do??????????????????????Help!!!!!!!!!!!!!!!

    There are several threads that have already dealt with this subject. You might want search for Olds, or 455, or engine swap, or something close within the Jet Tech or Gear Head forums.
    I entertained the same idea a while back, but decided I would go to a Chevy based engine in my next boat. If you manage a 455 it can be a great, solid motor. Likewise, if you don't manage it, the 455 will fail, it has flaws.
    Some possible sources of create 455 might be: http://www.remanufactured-engines.com/page22.htm http://www.enginefactory.com/ http://www.atk-engines.com/marine.html
    And then there is Mondello's.... http://www.mondellotwister.com/
    If you do go Chevy: http://www.ariasengine.com/century.htm http://racingengines.com/public/sales/wrldprd1.htm
    There is loads of info out there on the web. Good luck.

    You will never find an end to sources of Chevy parts. It is almost ridiculous how much is avilable. With Olds engines you just have to be a little smarter.

    It depends on how hard you run it, if it's in a day cruiser - it will be super reliable. If your running it hard, you will probably invest quite a bit of money getting the oiling system up to par. It would probably be better to upgrade to the 454 at this.

    As I said on Banderlog, if you go Olds, get Joe Mondello's Technical Reference manual. They also sell blocks but it won't be cheap. http://www.mondellotwister.com/CatTechAcc.htm
