If you would like to switch from a carburetor intake to electronic fuel injection (EFI), Accufab has developed two high flow throttle bodies to meet your needs. The Accufab four barrel 4150 throttle body is made from high quality 6061-T6 billet aluminum and then polished to a mirror finish, anodized black or red. Accufab’s quality is second to none. Only the best components are used for unparalleled reliability and performance. Manufactured in the USA.
The 4150 is a great street/strip throttle body. It bolts up to so many intake manifolds and flows more air than most 4500 carburetors. Accufab’s 4150 throttle Body flows 1215 CFM and has four 1-3/4″ brass throttle plates. This model uses late model GM electronics (TPS and IAC) which are included. Also, the 4150 comes with progressive linkage.
