    should be attempting a pour next week. Say Tuesday probably.

    I met a guy that owns a smaller non-ferrous foundry in Houston this past weekend that has helped a good bit. He introduced me to the direct pour method which should save me a considerable amount of time.

    This doesn't really help any of you since I won't really be charging for time unless I sell more than just a few of these pans.

    I'll keep you guys updated.

    We set records in XXO\BVGALT, and XXO\BVGCC. We are removing the head now to verify displacement.

    Top speed was 165. 949 mph

    Records are certified, so the FlatCad is in the books!

    Thanks for all the support, everyone!

    I had a mishap at work so I'm hoping to get back on it very soon. I did make a "practice" mold before my injury a few weeks ago and it worked well. I just need a better way to process the sand because doing ~600 pounds of sand by hand is never going to happen again.

    I will get it back going here soon, I'll post an update when I have one.

    congrats man! I saw it in the other thread, I'm really excited for you all!

    I have a new Ford top loader 3 speed with a Gear vendors over drive. Don't know the ratio. But they promised me it would hold 1000 HP. It's new and I'm not using it.

    Rich, I'm using a Ford crashbox, but it has a chevy input shaft, and bolts up to the muncie pattern. Do you know the gearing in the tranny? Does it use a standard Ford toploader bolt pattern?

    Do you think this is the right tranny for us? We sure missed you out there this year!

    Yes it has the standard '64 or so small bolt pattern. It has the passenger car slip yoke. Not the pickup flange. That's about all I know about it except it has been here for years and I have no use for it.

    Sounds like the ticket we need, Rich! Thanks!

    This is Dale's qualifying run in XXO\BVGALT, 160.737 in the 2-1/4.-THAT's a Cadillac flathead!

    At least you get to try it for the right price. Lets see Liberty beat that.

    Exhaust is .3405-.3415, and intake is .3415-.3425. I'm not sure what you mean by 'tip length'.

    You can find all this info on Keeper's site, www.flatcaddy.com, under Downloads, 1944 Light Tank Service.

    What are you working on?

    Cast Aluminum oil pans now exist.

    I have been MIA trying to finish with my schooling, but I set a date and apprenticed at a foundry in Houston TX using the pattern I made. The end result is 5 raw pans. I need to machine the flanges and drill for the drain but they should be good to go.

    The first pan floated so it is extra thick. It will be a wall hanger. I'll get pictures of the 5 good raw castings later, but I have two pictures of the mold. Everything was done in air-set sand.

    pattern-

    floated one- notice the thick flashing.

    mold, the 5 bottoms and a top.

    I've been trying to talk Collin into this, but he's been pretty busy.

    IMHO, what we REALLY need cast for these engines is an angle drive, that would bolt on the timing cover, like some Fords have.

    How cool would a crab style dizzy look up front, on an aluminum timing cover?
