What size did you make the runners again?

They're 1.75 OD tubing, which means about 1.625" ID.  That happens to match my TB bores perfectly, so it seems like a good idea.  I think Ed used the same size on one of his many intakes, though it wasn't being asked to generate as much power in those B drive days.  BTW, these split just before the engine to the primary and secondary ports.
