Thumbnail Filmstrip of 4B-9500 Accufab Largest Assassinator 5500 CFM 3.5" B Flys 7" Base- 38.5" SQ in Images
4B-9500 Largest Throttle Body known 1 is almost as large as a Birdcatcher
Assassinator 4B- 9500 - 3.5" B Flys 5500 CFM 7" x 7" Base Throttle Body* 38.5 Square inches of area
if you put it on a plate and cut your own holes you won't need the adapter - Much larger than a Dominator base
4B-9500 Better Air Flow for More Power. The Accufab 9500 series 4-barrel throttle body uses 3.5-inch bores and flows 5,476 CFM at 28-inches. There are no 4-barrel carburetors that can come close to matching that flow rating. If that s not enough, racers can mount two of them together for double the volume. 38 Square inches of Air Surface !!!!!!!!!!!!!!!
In many race classes, racers are limited to a single 4-barrel carburetor or a single throttle body. Accufab used a clean sheet of paper and came to the conclusion that the standard intake manifold opening for the largest carbs available (the 4500 series) was just not adequate. The 9500 will not bolt up to a 4500 style intake manifold, which uses a 5.375-inch by 5.375-inch bolt pattern. The attachment bolt pattern for the 9500 is 7.0-inch by 7.0-inch and the required intake plenum opening needs to be at least 7.25-inches square.
Accufab’s goal was to design a better 4-barrel throttle body without trying to make it fit on the existing 22-square inch 4500 series intake manifold inlet opening, an inlet opening that was originally developed in 1969. The correct 9500 inlet opening is 52.5-square inches.
This size provides a 250% increase! Racers, or intake manifold manufacturers, will come up with better intakes to match the increase in air flow. Also, racers are creative and will most likely use a sheet metal plenum style intake manifold.
Exceptional Quality. The Accufab 9500 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. Center-dump type progressive throttle linkage is included. Each throttle body weighs 4 pounds, compared to up to 13-pounds for a big 4500 series carburetor. Manufactured in the USA.
Application. These throttle bodies 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). Accufab has an optional adapter to accept the GM TPS if needed.ectly to most 4500 series ctake manifolds. The base to body has no idle air control provision. Also, it's designed to use a Ford style 5.0L 1986-1993 Mustang pigtail style throttle position sensor, sold separately.

Also a bolt-on throttle body for any 4500 intake manifold, however, the intake plenum directly under the throttle body may need to be chamfered a little (with a hand grinder) to accommodate the air flow of the 2 1/2" throttle bores. 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.
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.
