Does anyone make motor mounts to lower an engine?

[YerDugliness]

I'd like to use a high-rise Performer RPM Air Gap intake manifold and my current K&N X-Stream filter on my Cobra replica ( http://www.knfilters.com/search/prod...x?Prod=66-3150 ), but there is only about 1/8" clearance between the top of the air cleaner and the underside of the hood scoop right now with the Edelbrock Performer intake and Edelbrock carb. I guess I could use a drop-base air cleaner base, but I'd rather be able to use the stock Edelbrock base, which is only slightly raised but nicely radiused. The current base is not raised or radiused.

Does anyone make motor mounts that will lower an engine? I've thought about having new brackets welded to the frame to fit standard motor mounts, but if anyone knows of mounts that lower the engine, I'd rather try them first.

In the past I was successful in slightly lowering a 351-C that I stuffed into a Maverick by slotting the holes for the mount bolts, but I don't think that will be enough this time.

Just FYI, the current motor is an 8.2" SBF, a 1989 Mustang GT 5.0 that has been switched from EFI to carb.

The rear end is a Ford 9" mounted by a parallel 4-bar system. The bars all have adjustable ends, so the pinion angle can be adjusted rather easily if need be.

Thanks for any information you can provide or any suggestions you might have.
