New, Stronger Cylinders for Your Knuck

I received a set of S&S/Flathead Power 74 inch Knuckle cylinders into the shop last week, and thought there may be an interest in some comparison shots. The black powder-coating on the S&S cylinder on the left is a little too glossy for my taste, but will doubtless hold up well.

A nice touch is the cast in emblem which suggests (but does not copy) the original's MC (Milwaukee Casting) badge

Cast in number plate also pay tribute to the original, though on the Flathead Power cylinder the large "F" corresponds to Front cylinder. Note the crack in the spigot on the stock cylinder.

Even the pistons that come with the cylinders have a dome that is reminiscent of their vintage counterpart. On left is the new S&S cast 74" piston, on the right an English made replacement piston from back in the day.

Currently the S&S suggested retail for a set of these cylinders is $980 with pistons, or $850 for cylinders alone. Not cheap by any means, but certainly a worthwhile investment if you plan serious performance modifications.
