How much additional room is this unit going to save me over a typical vacuum brake booster?
Overall, approximately 4 inches more spacing for tall valve covers is available by comparison to the average vacuum brake booster! The space savings will vary from vehicle to vehicle. When used on a C3 Corvette, possibly the worst offender of all, it is now possible to run a tall deck big block Chevy with tall valve covers while still retaining a power brake system, and still have room!
