Any reason why I can't use the Edelbrolck FI intake manifold (PN 28155) on my Magnum with EQ heads drilled for LA intake? Perhaps (Magnum) accessory mounting problems? Anyone done this?
Check out Hughes website for the flow numbers on both manifolds at low and midrange RPM. The Beer Keg manifold can be easily modified to bump the peak power and torque range up about 800 RPM.
I remember researching this a few years back when I was using a slightly bigger cam that would still work with the stock valve guides etc. There was nothing currently available will produce more power at low and midrange RPM than the Beer Keg.
Having a competent tuner alter the factory programing so you can reflash the ECM using a hand held SCT Tuner will give you significantly more power too. I found it to be the single greatest power enhancement I did on a near stock motor.
Depending on the cam, exhaust and compression you run, themed and upper midrange power can potentially be higher with your Eddie intake. Is that manifold similar to the Hughes Airgap?
