    The additional materials have arrived for the BUbble Up Trans Am so this will moved to the back burner for a while, perhaps some small updates in the next few weeks. Here is where it's being left, hood and scoop pretty much ready, motor and trans have all the basics and the aluminum dash is ready to drill for gauges, switches and MSD electronics. The opening doors will be addressed once the BubbleUp caris done.

    I guess I should show a photo of the car that is the inspiration for this project. I should add that the fact McLaren Auction sponsored the car really had nothing to do with choosing this project. Fast Eddie was a character, almost larger than life. Stories of his antics are legion.

    You just keep raising the bar on this one, great update!

    The carbs were Holley 660 Center Squirters, a drag race only carb that had both sets of throttle plates open simultainously instead of staggered as in a normal configuration. Driveablity was sacrificed for throttle response. The other unique feature of this model carb was a single accelerator pump nozzel with four outlets, mounted in the center of the airhorn where you would normaly find the air cleaner hold down stud on all other four barrel carbs.

    Thanks Mike, I sure hope soby way of an update, after talking to the engine builder of the car the correct carb layout is side mounted carb but not Dominators
  6. Ian McLaren
    Printed, painted and detailed a Doug Nash five speed transmission and period correct Lakewood bellhousing. I also print some carburetor options for the intake but I think the Dominators are too new for this era, need to do a bit more reaserch

    Thank you John, so far this isn't planned as a fully detailed model, but these things have a habit of developing a life of their own during the process. I have already changed a couple of planned areas to a more detailed level. We will see.

    Yup, since that post I've had several people from the local tracks fill in gaps in the layout of the car, especially the interior and chassis, as the doors on the kit already open the interior will take up some extra time. I'm really fighting the urge to open the deck lid. So far Im replacing the kit firewall and have also moved its location rearward. I am pretty happy with the BBC and tunnel ram, certainly a step up from the kit engine. Also change the hood front hinged to liftoff

    My Bubble Up Trans Am funnycar project is on hold due to parts and paint. it's being set aside for a couple of weeks, This one just poped up due to a conversation with some friends. Starting out as a less ambitious project

    Hi Jeff, I didn't realize your were on this site, an oversight on my part since you have been here since 2015 apparently. The car looks great and the front wheels are spot on. I'll have to track dowm the rest of your posts.
  11. Ian McLaren
    Thank you John, so far so good.
  12. Ian McLaren
    Thank you Tony, more to come on them including images of the jigs used for fabrication and clean up
  13. Ian McLaren
    Thanks Daniel it was a fun piece to build.

    Basic headers fabricated and fit to the engine, still have flanges braces and detail to add, but the hard part is done. Rear pipe on right side has to have the tip shortened slightly (very minor) Headers were built in ajig to assure they were straight and level Both sides mounted and initially adjusted, final positioning will be done once they are permanently attached to the engine when details , flanges and waterline fittings are attached
  15. Ian McLaren
    Daniel the chassis looks great, the wheel and tire combo works very well and suits the era. The stance is very believeable and just has that "right" look. Excellent progress!
  16. Ian McLaren
    First of the header flanges drilled for the pipes, these serve two purposes, one is to add detail to the headers (even though the LPH1320 has superb details cast in) and second to act as part of assembly jig to set the pipe spacing at the head face while soldering. The head itself can't be used due to the heat involved. The spacing of the holes is 8.8MM C to C, to match the holes in the LPH1320 Keith Black printed heads

    Well it's official, I'm going with scratch built brass headers. Jig is set up and header height and exit positions have been determined. Test bending the first brass pipe to lock down the degrees of bend required to get the proper rear sweep and outward angle of the pipe exits. Should have all eight pipes bent and rough cut to size later today. I want to have the actual header fabrication jigs built in the next couple of days and the headers done by the end of the weekend .

    Hello Francis. I hope you are having a good and prosperous summer, we are all patiently awaiting your next update, be well my friend
  19. Ian McLaren
    Test fitting the steering and other major drivers compartment assemblies to confirm it all fits together
  20. Ian McLaren
    Yup those look just fine, they are a cool addition not often seen!
  21. Ian McLaren
    Daniel, I forgot there is a scale difference, you are putting so much detail into the 55, I was regarding it as a 1/16th when doing my calculations, the correct number for what I was aiming for in 1/25 would be .05".
  22. Ian McLaren
    As much as I remember the spacer itself was 1.25" tall and used two .025 reinforced valve cover gaskets, one below and one above. The ones in my model photo are oversized at .092 tall but they tend to warp. To repair that I sand them down to close to where you are I think (080") as per this photo or a scale 1.28". Hard to tell when everything is the same color but to my eye it might have to be a bit shorter. But the .080 I think may be workable.
  23. Ian McLaren
    The reason for the thicker spacers on the BBC was with the solid roller camshafts and required spring pressures the rocker arm studs would flex and eventually snap off and the pressured s also played havock with valve lash. Jomar solved both problems with their girdle the studs would support each other through the u-bolts that also locked down the valve adjustment. They made valve adjustment a little more tedious but the reliabilty gains were well worth the extra effort
  24. Ian McLaren
    Absolutely a great model, all areas very well done, excellent attention to detail and scale. You should be very proud of this project!
  25. Ian McLaren
    Some how it figures it would be you who is the only other guy to put Jomar stud girdle spacers under his BBC valve covers. I have a set for my next build as per the photos below. The car we raced in the early70s, I just love the authenticity you put into your models! I appologise for the huge photo but it was sent to me as one image but does show of the spacers quite well
