The Ford Barn

I have a question for the flathead gurue's , I have a 8ba motor with made in Canada on the heads , has aluminum intake 2 bbl. with 4 bolts, CC 9425 on the manifold, pulled 1 head, 4 inch stroke bored 3.250 with the pistons marked .040 , the motor turns over freely , has been converted to 12 volt coil and alternator . Has 3 speed trans attached , column shift . Valves all look good and marked ford script , see no visable cracks . What is this and how many cubic inches, and value , was going to use in my 40 ford but changed directions.

I think you are supposed to put this in the swap meet section. With a standard bore it would be 255 cu in. Now maybe 265-270? Anyhow you should list it in the swap meet with some photos. It will sell.

260 cubes, interesting intake. However without a good block the value is questionable. Sometimes known as "A pig in a Poke"

The 4 inch crank has value, again if its good. Always a crap shoot with flatheads.

We sorta have an oxymoron here. You say you have a 3.25" bore, yet a 0.040" overbore equals an actual bore of 3.227". Is it possible you mis-measured that 3.25" by a few thousandths? Nevertheless, if the bore is 3.227", the displacement computes-out to 261.72 cu. in. Now if the bore is actually 3.25", that computes to 265.46 cubic inches. DD
