Super E Manifold #1707, 88"/100" Evolution Big Twins 1984-99 (Size 397)
Original S&S casting with an index number of "6" clearly indicated on the flange face. According to S&S literature, this index number corresponds to a manifold size of 397 for 88" and 100" Evolution Big Twins.
Excellent condition with no evidence of use. So this is likely a new manifold.
