Been wanting to go EFI, found a deal I could not pass up, always wanted this set up but the price said NO WAY until this came up on Moparts, took one intake apart & started grinding for Max wedge ports, got a little done but the heat was to much, I will just have to pace myself & get done what I can,may take awhile LOL. I am SO exited to get this for the Charger smile

Nice.

Looks like they designed it to be made into MW size.

Yes I called Hilborn before I bought it & they said the max wedge was the same casting as the 440 port.
The shadowing in the picture makes it look like I did not follow the contour of the port, but I did.

Looks great, have fun with it.

Having said that, what do you expect to get by way of results (other than the known EFI benefits)?

I did a lot of EFI Individual runner intakes on Harley's back before I got sick, IR set ups & longer runner will idle MUCH better with a large cam, much better drivability, low & midrange torque is much better, I have posted this dyno sheet before , this is my old 2005 Dyna FXDWG, 94.2 cid EFI, the blue lines are with approx 8in long runner, the red lines are 24in IIRC, nothing else was change, my Charger is a street car , it is already a blast to drive , this should step it up a notch or 2, plus it will look awesome sticking out of the hood.

I agree, but AFAIK the only stack injection nearly large enough is the Crower for BBC, which has 2.90" butterflies.

Depends on how much power you want, the set up I have flows way more than I need for the power level I am at now, 2.9 butterflies are in the 1000 + hp, I am in the low 600, street car, overdrive A/C . Hilborn does make the 3" bore, My butterflies are 2.4375,the runners are 2.5 id, do the math my intake valve is 2.14, the id of the intake seat is 1.94

I agree....so cool and rarely see these setups poking through the hoods of Chargers. It will be sick looking! I admire your ambition. up
