The Street HP features an aluminium contoured main body design taken from the race winning 4150 HP and has a tumble polished shiny finish and screw in air bleeds for precision tuning capabilities. The metering system includes a timed spark port for a vacuum advance distributor and is calibrated for a hot street/strip engine setup for outstanding throttle response, drivability and maximum performance.
