Re: Question for vortec 06 swap people

ooops here .20c more; the EV1 and EV6 are still different from each other, but either can be wired in in place of the MultecII.

The EV1 injectors and plugs are technically an "older" design. They have usually 1 or 4 holes in them, which limits the injector spray pattern slightly. This effects how accurrate the injectors can be at low PWM or duty cycle (i.e. if you have waay to much injector, it will be very hard to tune it "down").

Ev6 injectors have 6 pintles, which has an improved spray pattern, being slightly larger and more even. They do have a slightly different body from the EV1 injectors.

Some folks swear the EV1 injectors have a habit of being directional, and putting more fuel to one side of the chamber. You can source the EV1's off a lot of the late 90's-early 2k F*rds. These are the "blue top" or "green top" or "SVO" or "SVT" injectors, depending on what those numbskulls decide to call their uprated injectors. F*rds run a lower rail pressure than our engines, so ALL F*RD INJECTOR RATINGS ARE 5-10% LOWER THAN YOU WILL SEE ON AN LS MOTOR.
