Installed this on my 78 C10 along with the chrome master cylinder. Even with a pretty aggressive cam in the BBC 505, it still has very good braking power and looks great too.

This is worth buying

I used this brake booster on my 54 GMC pickup after converting to disc/disc brakes. The eight inch diameter booster clears the tall valve covers and the OEM fender bracing rods.
