    Default Pfaff Blown 509

    Listing for my Dad his Pfaff 509 Blower Motor. Motor was built new in '95 for his 21' RT and had approx. 60 hours when he sold the boat a few years ago. The engine has been at Pfaff's shop until a few months ago or so, now in my garage.

    Details from the Build Sheet:

    509 Cubic Inch Gen.V Bowtie Block
    Crane Hydraulic Roller Cam
    J&E Pistons
    GM Crank with Carillo Rods
    Heads are listed as Merlin Dart Square Port??
    B&M 420 MegaBlower with Holley 4779 Carbs
    Intercooler

    Originally is was 9% underdriven and dyno'd at 750hp (6,000rpm) and 742ft/lb (3,900rpm). Max boost with this setup was 5.2psi. It's a torque monster as the dyno sheet starts at 2,900 RPM and its already making over 700ft/lb. He switched to 1:1 pulley's and had it re-jetted but never re-dyno'd.

    Currently it is setup pretty ready to run - Dooley scoop, blower guard, power steering pump, water pump, etc.

    Please post or PM with any questions. I'm sure arrangements can be made to see it for interested parties.

    $7,500 OBO

    $7,500 will get it complete. Will consider separating the long block and blower/intake.
