If you would like to switch from a carburetor intake to electronic fuel injection (EFI), Accufab has developed the 6500 high flow throttle body to meet your needs. The 6500 will bolt directly to most 4500 series cast intake manifolds. Also, the base to top height dimension and the air cleaner flange are the same as a 4500 series carburetor. Please note, some machining or grinding required to widen the upper area inside of a cast intake manifold plenum to clear the 2.56" diameter throttle body blades.
Do you have a 4150 bolt pattern? No problem! We offer a modified version of the 6500 that is Dual Mounting and will fit both 4150 & 4500 bolt patterns. The Dual Mount is a custom part and may take a few days to ship from date of order.
We also have the 6500 available in a Short version, measuring 3" tall.
Better Air Flow for More Power. The Accufab 6500 series 4-barrel throttle body uses 2.56-inch bores and flows 2,656 CFM at 28-inches.
Exceptional Quality. The Accufab 6500 throttle body is made from 6061-T6 billet aluminum and polished to an eye-catching finish. Accufab's quality is second to none! Only the best components are used for unparalleled reliability and performance. Each throttle body weighs 4 pounds, compared to up to 13-pounds for a big 4500 series carburetor. Manufactured in the USA.
Application. This throttle body may be used with either EFI or mechanical fuel injection. For an EFI application, the throttle body is CNC machined to use a Ford Mustang 5.0L 1986-1993 throttle position sensor (TPS). However, Accufab has an optional accessory to help adapt this Ford style TPS provision to be used with GM electronics instead. For example, we offer a TPS adapter to use your GM TPS.
Accessories Included: 6500 throttle body gasket.
