    Default Pfaff machined 460 cu in BBC shortblock.

    This is a BBC Gen 6 block machined .030" over by Pfaff. It's also been align honed and surfaced, with new cam bearings.

    Crankshaft is a GM cast crank, freshly ground, with oil holes chamfered.

    Connecting rods are 3/8" GM that have been resized with new ARP bolts. Pin end has been fitted for full floating rods, and has oiling holes added.

    Pistons are new SRP small dome .230" tall.

    New Total Seal Moly rings.

    New Clevite main and rod bearings

    New 1 pc rear main seal.

    New Dooley 10 qt jet pan

    New Melling M77HV oil pump, steel collar drive, and oil pump stud.

    New SFI flexplate

    Used Gen 5/6 damper

    Mint used IMCO timing cover, just back from polisher

    1pc oil pan gasket

    Rotating assembly balanced

    Camshaft custom ground to your boat and application

    Billet timing gear set

    Complete as listed, with block deburred and paint, all bearing clearances measured, crank thrust set, camshaft degreed, oil pump dis-assembled and checked prior to installation.

    Get your pencil out and add this stuff all up. The pan is a jet pan, but should clear in most stern drive applications. The engine could be completed if desired.

    All fresh with new parts. All Gen 5/6 blocks are 4 bolt main. Compression will depend on which heads, but just above or below 10-1 depending on chamber size.

    Guess I need to assemble this and post photos. I was kind of holding off so it could be painted whatever color someone preferred.

    Anybody need to get on the water quick, this one is machined and ready to assemble, could be ready as soon as I can order a cam to match your application.

    Good time to get a fresh engine ready for the season. I will also sell this as a "kit" or complete engine.

    I am going to go ahead and assemble this soon, with a set of Merlin iron heads that have a fresh valve job on them, probably a polished single carb intake. If someone wants a fresh engine for the season, I would like to paint and taylor the cam selection to work with the buyer's boat

    Factory 454 crankshafts are all externally balanced. Most would consider it cost prohibitive to add enough heavy metal to internally balance one for an engine such as this one.

    Once you start changing to aftermarket crankshafts, like a forged stroker crank, you will find most of them are internally balanced.

    Looks like I will have some time to assemble this in the next week or so, been holding out on ordering a cam for it so that it could be ground to best work with the purchaser's combination.

    Good medium performance package. Can add or remove parts as necessary for your application.
