To get more power out of your SHO you need to get more air in. Our Big Bore butterflies do just that. They are bored an extra 3mm over stock to get more in more air above 4k rpms.
The BBBs are bored out using a CNC mill so you get the smoothest flow as well as new laser cut butterflies. This allows everything to fit up properly and get a good seal unlike other who use stock plates or port out the BBBs by hand.
Please keep in mind that we use cores from other customer for the BBBs so the condition of them will vary and we do our best to clean them up.
If you option to send your cores in first we will not send out your BBBs until we receive the cores.
If you pay the core charge to receive the BBBs immediately, your cores must be returned to us within 45 days to receive the core return credit.
Please send cores too:

Tech Notes
The BBBs have shown a gain of 10hp above 4k rpm. When installing BBBs you should install a ported intake to get the most out of the BBBs.
The horns should be removed during installation.
We are currently making another batch of BBB's so there may be a two week delay in shipping new orders.
