I am hoping someone can enlighten. 1984 regal orig 3.8NA/TH200 swaping for SBB 350/2004R. In all my web searching this department I have read about this pass valve cover to airbox clearance issue. So my question is does any one here know with this particular ride will the Poston or TA angled valve covers remedy this? Or would a "HVAC box" from a turbo car help remedy this clearance issue? Will the engine fit and just leave the valve cover "permanent" so its not removable? Also has anyone used poly v6 engine mounts with the SBB?
