Plumbing OMP into Edelbrock Q&A

I would think the stock oil injectors are a better choice.
Generic brass fittings would have boost pressure trying to force the oil back down the OMP lines, where the oil injectors would keep this from happening. This theory seems to be supported by Mazda's use of the oil injectors in the intake/housings of factory turbo engines, rather than simply having a nipple to attach the OMP lines to the intake.
Since boost is part of the equation, another option that needs to be considered, would be makng OMP fittings at the top of the carb similar to the way they are situated on a 12A 1st gen Nikki. Of course, this will mean oil will be going thru the S/C, and who knows what that might cause.
