What is it about the magnum manifold that doesn't fit? I've got a pair in my garage I'm considering for my build, but I'm also going coilers and rack and pinion.
Sorry, I should have said, drivers side won't fit in "my" application. The rear exit magnum manifold works fine on the passenger side of my car with the 90 degree oil filter adaptor. The drivers side is impeded by all the clutch rods, zbar, and probably more.
I cannot make a blanket statement and say it "never" will work.
