    Default New Build

    OK...we have a plan for the new build and here's what we got.

    JNW Engine here in Santa Rosa will be doing all the machine work. Thanks Terry for recommending me to him.

    The block needs an align hone bad. It should've been done on the original build since I switched over from main cap bolts to studs, but my previous machinist never told me that I'd need to do that so I didn't know it needed to be done. But we found very uneven wear on the main bearings which points to the fact that the block definitely needs it. So that issue will also be addressed.

    0.060" over 454 (468)
    Eagle Forged 4340 crank
    Eagle H-beam rods
    SRP Small Dome Pistons
    10:1 compression
    Comp Cams Xtreme Marine XM278H cam
    Comp Cams Pro Magnum lifters
    Edelbrock Performer RPM aluminum heads
    2.19" intake, 1.88" exhaust valves
    Scorpion 1.7 roller rockers
    Comp Cams Pro Magnum 3/8" chromoly pushrods
    Melling 10778C high volume anti-cavitation oil pump

    Some parts from the previous motor will be used:

    Edelbrock Performer RPM Air Gap intake
    Comp Cams double roller timing chain (if it degrees in right...may have to get a different timing set due to the align hone)
    ARP main cap studs
    Holley 750dp marine carburetor
    Canton marine 9qt oil pan
    Scat FP454SFI flex plate
    Powerforce 8" harmonic balancer
    MSD 6M-2 ignition w/R2R distributor
    MSD Soft Touch rev limiter

    Hopefully I can get her running and back on the water by the beginning of May. We're estimating around 500-550hp.

    The pump is also going to require a rebuild since the impeller was coming apart and the shaft is out of round beyond spec. The wear ring is good though and we'll be converting from the mechanical shaft seal to the traditional rope seals in an attempt to correct a holeshot issue I've had since day one. But I'll be running an A impeller this time (previous cut was an AB). Hopefully this thing will jump right outta da wata with neck snapping acceleration.

    So,not to be rude but how much is all this costing you.
    When I got my jet boat (2001) it ran alright the first time or two until it sucked buckets of water into the crank case-I don't have pictures but there were holes where there shouldn't be.
    1700 bucks or so later and the beast was back together and stayed put til I sold it in in 06 after we got the "new" hot rod.

    No "rudeness offense" taken. It's gonna cost quite a bit (about $4500 is my estimated total cost), but if cost were my main concern with this stuff, I'd have gotten out of BOATing a long time ago. I know I can build a stock motor for a lot cheaper but then I lose the top speed and some of the acceleration factor that I gained by doing the full powerplant rebuild in the first place. Had I had known more about building engines when I built the last one she'd still be running today and this wouldn't be an issue.

    As I've told many people before, monetary value of the boat itself and cost have always been seconday to how much sentimental value this whole project has to me.

    Are you going to do the pump work, yourself?

    Sorry I missed your call last night.

    Just My two pesos but
    After ussing a Hyd roller cam in my last build SBF in a 1970 block
    I would never go back to a flat tappet hyd cam
    initial cost is more,but justifyable IMO
    also a custom ground cam to match your heads/intake is money well spent too
