Part # BPI-K-BP8021SP
Similar to the 51-423-11 but with wider lobe separation, smoother idle, a broader power curve, and more vacuum
(HR) (Std Firing Order/ Std Journals) 276/282, 224/230, .503/.510, 114LS with 1.5 ratio rockers
Lift with 1.65 ratio rockers .553/.561
Slightly more vacuum than a 112 and produces a little smoother idle.

With the 400 and that cam you will find your going to gain about 15 to 20 HP switching to OTB aluminum head over the stock 62s. Pretty expensive HP.
