    Default 572 built wrong!

    so, I was in havasu last week. had to get towed back in.
    Machine shop that built the motor screwed up everything. Timing pointer was off by 10 degrees, couldnt rev the motor up. intake manifold wasn't properly siliconed (lots of water in oil). Ruined 4 roller rockers 4 pushrods, and more. I wouldn't let that guy fix the motor in my chainsaw!
    Now the motor is getting redone at Paul Pfaff.

    Are you referring to a crate chevy 572 620 horsepower? I have always been curious what would need to be done to one of these to get it to perform reliably in a boat. Has anyone done this and how much should it cost? What were the results?

    There are "Chinese" cranks and rods that will live fine at 1Khp, and then there are "engine builders" who can ruin a $5K billet rotating assy. Sorry you went through this.

    This not a crate. Dart block. Rpm rods crank. I'm sure it will take some hp. I'm just not going to find out if it's good or not, this is why I'm going to a callies crank and rods. I just wish this guy would of told me he is planing on robing right in front of my eyes. This is what you call theft

    This makes me wonder if the builder broke the engine in and set the timing and all or if the customer took the long block and told the builder not to worry , that he has it handled.
    As you should know Steel, some customers could tear up an anvil with a stick of butter

    doesnt matter if its a callies or not , if its not set up correctly it'll eat itself.
    If Pfaff is doing the job , there'll be no worries.

    The RPM crank and rods may have survived just fine, but maybe ovrkll77 was not educated to the differences by the builder.
    I agree on the timing, only I was thinking of the other direction...a blower engine (or any engine) can 't stand excessively late timing which puts a ton of heat on the ex side, possibly causing the ex valve failure? Not being able to rev the engine might also be indictive of late timimg. 10* is a lot.
    Isn't the Callies Dragonslayer a Chinese crank?

    I am educated when it comes to blower motors. I was stupid as of relying on a shop that has been building stroker
    Motors since 1948. I should of goolged his name before I dealt with him

    What did the motor builder have to say about the motor, I hope you
    have some kind of recourse on the improper build. if the timing
    marks are that far off you would think he would do something.

    Good Luck .
