Unlike the standard Super E and G carbs, the E-Extreme and G-Extreme carbs have the same mounting bolt pattern. This allows both carbs to use the same manifold. Manifolds for E-Extreme and G-Extreme carbs are machined to fit the ports of S&S Special application B2 heads only. Due to the special shape and larger port size of the B2 cylinder heads, manifolds are only available for large displacement engines with fairly tall cylinders. Manifolds are stocked for S&S 124", 126" and 145" engines. Manifolds for other applications may be special ordered for engines with cylinder lengths between 4.945" and 5.838" (based on crankcase deck height of 6.000"), or with port-to-port measurements between 3.878" and 4.610", as measured with the S&S Manifold Measuring Tool

NOTES:
Cylinder lengths for S&S 124” 41/8” bore engines are based on crankcase with 6.000” deck height.
Cylinder lengths for S&S 126” and 145” 43/8” bore BT SA engines are based on crankcase with 6.375” deck height.
E-Extreme and G-Extreme manifolds are for S&S Special Application B2 cylinder heads only.
