The only purpose built kit I know of is the dual Paxton setrup from Cobra Automotive.
Cobra Automotive Shelby Mustang brakes & suspensions
Very pricey at some $8500.
There are the Vortec kits guys convert to fit. I believe this requires fabbing or modding the mounting plates and tubing. Ask around at 332-428 Ford FE Engine Forum
Few guys there are into them and can help you out. Look for Jay Brown there he runs one on his 511" aluminum Shelby engine. Good luck.
