    Parts are starting to come in for this one also.

    Outline of the motor:

    Crower Forged Crank- 4.365 Stroke, 3" mains, 2.200 rods
    Race main and rod bearings
    Total Seal Rings with Steel top compression ring - 1/16 ring package for long life.
    54MM TA Performance Solid Roller cam and lifters- specs to follow
    Billet timing chain
    O-ring block, copper head gaskets
    Custom SRE wet sump oil pan.

    Re: Pistons

    TSP/Diamond Custom blower piston


    68CC dish


    12 Lateral gas ports- 1/16 ring package


    HD blower piston forging- 638 total gram weight

    Rings are from total seal, with Steel top ring for Supercharged application.

    Piston Pins

    Pins are important to not overlook in a blower motor.

    These are H-13 Tool steel.

    .205 wall thickness.

    Shown here next to the Standard NA 470-555 pin.


    A little heavy at 187g, but a piston pin is not a wise place to try and save weight.. break one and it's a bad day.

    And we are swinging an alum rod. So the assembly is reasonably light, for a 6500 rpm engine.

  4. Jim Weise

    Jim Weise 1000+HP


    Rods are GRP Aluminum units.

    6.600 length
    .990 pin
    2.200 big end

    These are the Pro Series 5301 rods, made from their Pro material. Thicker pin ends and a more dense material make these rods the ones to get for street strip service above 1500 HP.

    While these are shorter than the NA 555's 6.800 rods, the more dense material actually makes them heavier- 670 G vs 630 for the 5001 series rod.

    Don't spare the rod.. or you could spoil the motor!


    As compared to the standard 5001 series rod, it's not difficult to see the extra material at the pin end.

    I dunno...those rods look pretty heavy


    ps Beth wants to eat some crunchberries outa one of those pistons:bla:

    Jim Weise 1000+HP

    No crunchberries.... Lucky Charms maybe.. :puzzled: :laugh:

    Actually they would work good to hold the frosting for cupcakes.. but ya, that's right, she doesn't make them for me anymore.. :rant: :Brow:

  7. Dana/Beth Andrews

    Dana/Beth Andrews Huc accedit zambonis!

    HELLO!!! Didn't I just sent you an email the other day asking about said cupcakes??? Hmmmmmmmm.... you never replied.

    I don't trust my boys to deliver cupcakes, so I have to do it myself.

    Just like you said to Mike T. about the Tomahawk... build it and they will come... :grin:


    P.S.. I guess Lucky Charms will be OK
  8. Jim Weise

    Jim Weise 1000+HP

    Never saw any email Beth...

    check the address, it may have changed since you emailed me last.. since I am apparently of no use to you, unless your car is broke.. :ball: .. never call, never write... and..

    I can't get a cupcake to save my life..


    :rant: :Dou: :rolleyes: :puzzled:

    OUCH!!!!!!! Knife thru the heart...:ball:
    I sent it on 11/22/10 at 11:42 am, it was a reply to our talk of Dip Sticks...
    And I quote...:moonu: :bla:
    "Hmmmm... so, I forget is it vanilla cupcakes & chocolate frosting with sprinkles or was it all vanilla with sprinkles."

    Now answer the question mister... or will these work?


    P.S. Ya know I still love ya, but there is no way you are sweet talking me into supercharging the wagon....heehee :grin:

    Jim, Have you thought of going to turbo's, yes I said turbo's.. I talk with Mike Morgan and Adam Wyatt when I can, about turbo set ups. I have learned one thing about Turbo's that are a big advantage over any power maker except nitrous! The turbo only requires 5 to 7 hp to operate no matter the size you are dealin with. where superchargers pull atleast 100 or more on the high power ones and the pully belt puts tons of stress on the crank snout, where the turbo is nice and gradual on the power output all the why down the track. and is easy on parts not like the rest of the power adders out there. Just a thought.....

    GSXMEN Got Jesus?

    I'm a big fan of the Prochargers, but I've got to agree with the idea of a twin turbo setup.

    555 cubes and a pair of hair dryers......yeah buddy!!:bglasses:

    Jim Weise 1000+HP

    Ya, thought about it, and if I was after 2000 HP then yes, we certainly would be looking into turbocharging.

    Dave Mongeon went that way with his setup.

    But for what we are building, the simplicity of packaging on non-intercooled, low boost, S/C setups is appealing.

    I probably will turbocharge my tube car, when that time comes. That car is a few years off yet.

    Awesome build ! Approx 15 K for a short block like this , but what about using this block for street 470 for a bit less money ?

    Any updates on this build? Cam spec, boost, dyno numbers?

    Hey Jim, did you ever get a chance to finish this one up? Was just curious if you had any updates, or any other new ones going together.

    Just saw this ... sorry for the late reply.

    This motor is for a project car in the shop, so no, we are still working on the car, no real rush on the motor.

    Will be later this spring.

    I am curious what a motor like this would cost turn key?

    Sounds like what I'm looking for.......
