4bbl Slant Intake

I don't think there is a problem, but don't know for sure. I do know, there is a problem with Clifford shorties and power steering on the 66 and older "A" bodies. The front collector hits the top of the PS gear box.
PS: As far as I know, The Aussiespeed headers are the only currently made header that fit with a 170 engine in the early (66 down) "A" bodies, but the Clifford shorties can be modified to fit without PS.
