Driven my recently finished DRB Cobra for 300 miles.
It has a stroked 351W - Now 427
Dynoed at 520hp / 540ftlbs Torque
The motor runs beautifully but boy is it thirsty.
It has a Speed Demon 750CFM.Mechanical second stage actuation.

Average consumption to date 3.5MPG (USgallons).

The intended use for the car is 70% street -30% track day.

Just wanted some feedback from the club on the fuel usage similar motors (like the ROUSH 427's).
I dont have the car to compete in Economy runs but it would be nice to enjoy cafes and wineries insread of fuel stations.
