Here is a 351W, Ford GT-40 EFI set-up with an offset Hydroboost Bracket. NO clearance issues what so ever, especially with a Carb. Can get to everything easily.
Body lift or not does not matter either as far as the Hydroboost goes. Pictured with a 1" Body Lift.
Zero mods to the Bronco to install.
This Bracket can be found on eBay. Great quality, VERY easy to install and takes the Astro Van hydroboost and MC.
