Does anyone have a WD intake/exhaust manifold laying around that wouldn't mind measuring the intake port diameter for me? I am very curious to know what this diameter is. Thanks J

1-3/8" and the Exhaust ports are the same size.

You sure this is the intake manifold port dia. The cylinder head is 1 3/8. I measured the intake on my WC and it is 1.114 rather small. A lot of the old timers tell me that a manifold off a WD will perk up the WC a few horses due to the better breathing manifold. I am thinking of boring out the intake ports on my manifold so they are more port matched to the cylinder head. I hope this won't reduce my velocity at low rpm.

I measured the WD-45 manifold last night by mistake. It was a little dark in the back corner of the barn at the time. The "original" manifold for the early WD (with "short" head) does have 1-1/8" intake ports. However, it does have 1-3/8" exhaust ports. Incidentally, both the intake & exhaust ports in the "short" head measure 1-3/8" as they do in the "tall" head. Probably all the aftermarket exhaust manifolds are made to fit either WD or WD-45 and they probably have 1-3/8" ports throughout but I don't know that for a fact. The WD-45 and some aftermarket manifolds do have larger throats at the carb side to accomodate the larger carbs used on the WD-45s. Sorry about the previous misinformation! Brian G.

Yep, This intake/exhaust manifold is off an early WD which had the "short" head. I would have thunk that it would be the same as a WC?! Now I didn't use an inside micrometer; just my trusty old tape measure, but 1-3/8" is as close as I could measure. Brian G.

Today's Featured Article - Major Problems - by Anthony West. Following the aquisition of the two Fordsons to my collection I found that I was struggling to move them about. I had considered the possibility of driving the "F" to and from shows but anything other than local rallies was totaly impractical due to its sedate pace. I had also considered buying a landrover and trailer, but the price of a ... [Read Article]
