On my "Screamin' Six" engine, the Offenhauser intake consistently shows #5 running lean, the other cylinders are more or less even. #6 is always the richest.

I've read in the past about epoxying in popsicle sticks to alter the flow in the manifold, and while at work this past week, built up a good supply of ice cream sticks from convenience stores. (I try not to work TOO hard!)

Any particular kind of epoxy to use for continuous contact with gasoline? Can this be a permanent modification? Any ideas on how to best position the sticks (and what dimensions) to add fuel to #5? I have my own ideas but would like some confirmation before proceeding. Thanks.

I would do some grinding inside the manifold first. Open-up the entry to runner #5. Grind the divider walls and the floor to direct mixture into that runner. I used a carbide burr on the end of a flex shaft and guided by a handle to get to those tuff to reach spots.
Next try some staggered jetting in the carb. After that comes the epoxied-in dams. Epoxy dams are temporary only, once you get things working right, slot through the manifold wall and insert some alm. "wedges" then weld-up the seam for a permanent fix.

We are lucky on this one, Chrysler already did the work. Check out <A HREF="http://www.speakeasy.org/~kesteb/dart/d ... bs.html</A> .
