Thank you the tunnel wedge question worked. I personally am not into who has more horse power than who... I think that 740 HP is excessive for a street car to begin with. But that being said the motor you have is very nice.

I already have a nice set of Shelby heads that will make every bit of 650 HP and 650 torque, however my builder prefers the Blue thunder over the BBM. The BBM is a very nice product and would be my second choice.
