The fuel injector is also timed with the intake valve opening, giving the ultimate control and is the most efficient way to deliver fuel into your engine. This location provides a more efficient mixture control thats unaffected by varying intake manifold runner temperatures and length. Key to the improved performance of a system like this is the fuel injector location, which is at the end of the runner on the intake manifold right before the air flow stream enters the combustion chamber. Pro-Flo 4 EFI systems feature a high performance Edelbrock intake manifold with a 1,000 cfm throttle body, fuel rails and individual injectors for each cylinder. The OEM’s only utilized throttle body style injection for 9 years before transitioning to sequential port fuel injection for improved drivability and efficiency. Typically, the center cylinders run slightly richer than the outer cylinders, hindering tuning for peak fuel economy and peak performance. Edelbrock carburetor hardware kit includes (4) 5/16-18 x 1-3/8 studs, (4) nuts, and (4) lock washers. Will the bracket need a kickdown stud for the th400 or no, Im getting mixed answers. I have a 1972 c10, short bed, 350, th400 transmission and I am confused about throttle linkage, with I need to buy a bracket or will the original cable fit. This can also cause the air/fuel mixture to separate as it flows to the cylinders, resulting in an uneven mixture between cylinders. Getting a new carburetor and Im pretty set on a 1406 edelbrock preformer carb. Another drawback is the delayed throttle response since the fuel must travel through the intake manifold to the combustion chamber. Mixing fuel this way allows for it to puddle and condense in the plenum of the intake manifold, a recipe for hard cold starts. On most cars, youll need to remove the air filter to expose the carburetor and adjust it.
#EDELBROCK CARB FOR A 69 EL CAMINO 350 MANUAL#
My advice is to look for a Haynes manual covering the 71 model year. I put in a Chevy 350 4-bolt main crate engine, Edelbrock intake and carb, and Hedmann headers (it ran like a scalded dog LOL). It’s the most universal type of Electronic Fuel Injection system, but it’s not ideal for high performance engines. I had an 81 El Camino and wish I had never sold it. This design delivers the fuel into the air flow stream in the plenum similar to a carburetor. Throttle Body style EFI systems feature fuel rails and injectors mounted directly to a throttle body.
