  2. GN7 On the Dyno
    Picked up a boat that I liked on the cheap with a "non running engine", which was a twin turbo 454 with 990 heads and crane roller rockers. So I started taking it apart today in hopes of finding good news, instead I found 5 pounds of water in the oil pan, exhaust manifolds, turbos, exhaust...

    So I was out at the lake and my tach started showing 3000 RPM at Idle. The engine was idling perfect. Is there an adjustment on the tachs, possibly one of the kids good have bumped it? or is it just time for a new one? Any thoughts?

I am turning off the course, slowing down and hear on the radio "are you ok?". WTF.... again "Steve, are you ok?". I...

    Many post about too much power to a cast AL impeller will destroy it and the bowl but why would it sink the boat?

    I bought an "Officejet J4540" HP printer a couple of years ago, and although I can usually coax it to print, it now refuses to SCAN for copies... I'll bet I've made no more than 2 dozen copies in this printer's life, and of course it's out of warranty... I called the "help" tech line and after...
