I've got an 83 Camaro with an LS3 swap going into it but don't have any idea how big of a brake booster I can do or who makes a good one. I'd like to do at least a 8' dual diaphragm booster or bigger if I can. My brake kits are not stock, they are Wilwood superlites and I would like to get a Wilwood master cylinder as well. Anyone have any experience fitting brake boosters for this kind of build?

 

The brake booster does not interfere with anything associated with the engine swap. You can keep what you have if it is still working.

Boosters are not a "high performance" item. All they do is assist pushing the brake pedal. The more surface area inside the booster, the more it will assist and the softer the feel of the brake pedal.
