Good subject matter here. I too am thinking of putting a Hemi in my 70 Challenger RT/SE. It was an original 383 A/C car. Now if I understand right I will need the bracket behind the booster that angles it a little higher? Then where the blower motor is there (will be) or (might be) problems with clearance? I have the stock K-frame and had thought of going with the schumaker or the other engine mounts. Has anyone run the aftermarket A/C unit and mounted it down by the fuel pump and just run an electric fuel pump?? And I suppose if I understand right I cannot run the stock big block pullies etc. All this has me thinking twice now...... With the aftermarket engine mounts etc, would there be any issues with running a shaker setup? Questions questions....I just dont want to cut up fenderwells or have issues with the blower motor.
