Hey guys, I'm looking to convert my older 5.0 to fuel injection and am looking into the Holley HP EFI multiport kit, the main deal about this kit is that you take a single plane intake and drill out the holes for the fuel injectors, the only problem I'm having with this is that all of the single plane intakes that I see available are for higher rpm ranges.
Reading over the documentation in the instruction manual for this kit reads
*********************************************************************************************************************
"The easiest style of manifold to convert is a single-plane type intake manifold. A single plane intake manifold is not recommended with mild engines with carburetors, as they usually experience a loss in low-speed torque. Some of this is due to a poor vacuum signal to the carburetor. This is not a problem with EFI, as the EFI is programmable and the proper amount of fuel is easily programmable.
A dual-plane intake manifold has longer runners that enhance lower RPM torque. However, it is difficult and usually impossible to use a solid length fuel rail with a dual plane intake.
Testing has shown that EFI overcomes much of the typical loss in low RPM torque that usually occurs with a carburetor and a single plane intake."
*****************************************************************************************************************
So does this mean that the RPM range of the intake doesnt matter and that the fuel injection will make it so that I have good torque throughout the whole RPM range?
If so than I might as well go for an intake that has the holes drilled out for multiport injection. Such as
Edelbrock 29285, Edelbrock Victor Series EFI Intake Manifolds | Edelbrock - Free Shipping on All Orders @ JEGS
or maybe the intake offered by FAST
Single Plane EFI Intake Manifold, Ford 289/302 Manifold Fuelairspark.com
Any help with more information on this would be extremely helpful
