    Low Power
    by Cape Codder
    I have just returned from the Model A New England Meet at Lake George, N.Y.
    My problem was climbing some of those hills out there. I climbed several in 2nd although only doing 20-23 M.P.H. at high R.P.M. (no tack but I could tell).
    I climbed one at only 18 M.P.H. because I couldn't get the transmission in 2nd.

    I haven't checked my differential ration yet, but other than...

    B Head or is it a Model B Head?
    by Tom Wesenberg
    Sometimes people ask about a B head, but they aren't specific whether they mean the Model A high compression head with the "B" cast in it, or are they talking about the Model B engine head with the large "C" cast in it. Besides the letter cast in each head, they are very easy to tell apart by the water pump.
    The Model A head with the "B" cast in it has the regular...

    Re-Torque head hot or cold.... more info
    by tbirdtbird
    Tom W in particular will be interested in this.

    The debate, at least in the Model A world, will rage on in perpetuity, despite that the Service Bulletins state to re-torque hot.
    Anyway, I was wading thru my Motors manuals, going back into the early thirties, looking for some total advance comparison from earlier Stude 6-cyl with a 6.5 CR head, to the upgraded 8.3 head that was used...

    Stuck head
    by 2manycars
    A few years ago, someone gave me a truck load of model A engines that had been poorly stored. I saved 2 of them, but the rest were so rusted that I could only save a few parts from them.
    My brother is more persistant, and sent me these photos yesterday of his attempt to remove a stuck head. I think the new engines being cast by Tod will solve this sort of problem.

    High compression head installed.
    by AzBob
    New Prus 8:1 aluminum high compression head installed. Can maintain 35 mph on hills I used to have to downshift into Ruckstell with. A noticeable improvement in performance all around. The aluminum head weighs 12 lbs. The old 3.98:1 cast iron head weighed 28 lbs.

    Block or head layout
    by bettlesr
    I am looking for a drawing of the stud locations vs the center line of the cylinder bores. I have a Winfield 7:1 crow's foot head that I need to have flycut to clear the pistons that stick up .062" above the block. I have been using a standard gasket, a solid copper gasket and then another standard gasket. That is not really working well at this time. It left me with a crack between the water...

    Painting a new cylinder head
    by 29er
    There's been lot of great discussion lately relating to my current project: changing the head. I've got a brand new 5:5 Snyder's head coming that will need to be painted. Does it need any prep or primer before applying the Ford green top coat?

    Question on performance improvements
    by Mickey
    Would the use of BOTH a high compressor head AND a Model B intake and carburetor give you any significant improve over the use of just one of the two? Either the head or the Model B components.
    P.S. I have both but am leaning towards the head and a remanfactured Marvel Schebler carb. On a Model A manifold.

    A good smattering of hopped up Model A's (plus other marques and some wonderful motoring characters!) in this collection of photos taken at the Romo Motor Festival, Denmark (2016).
    It appeared in my F B feed. That's FaceBook, by the way, although like a lot of us, I do still frequent the "other" F B !
