Brand new in factory box.\u003c\/p\u003e\n\n\u003cp\u003eThe Street HP takes the contoured main body from Holley's race-bred 4150 HP series and tames it for street and light competition use. Tumble-polished aluminium construction drops around 40% of the weight of a comparable zinc carb, and the screw-in air bleeds make it genuinely tuneable rather than a set-and-forget unit. Calibrated out of the box for a hot street\/strip combination — strong throttle response with real drivability.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePart number: 0-82851SA\u003c\/li\u003e\n\u003cli\u003eModel 4150 HP, 4-barrel, square bore flange (5 3\/16\" x 5 5\/8\")\u003c\/li\u003e\n\u003cli\u003e850 CFM\u003c\/li\u003e\n\u003cli\u003eMechanical secondaries (double pumper)\u003c\/li\u003e\n\u003cli\u003eDual feed fuel inlets — 5\/8-18 inverted flare\u003c\/li\u003e\n\u003cli\u003eThrottle bore 1.688\" \/ venturi 1.563\"\u003c\/li\u003e\n\u003cli\u003eDown-leg boosters\u003c\/li\u003e\n\u003cli\u003ePrimary main jet 82 \/ secondary main jet 82 \/ power valve 4.5\u003c\/li\u003e\n\u003cli\u003eNo choke — petrol only\u003c\/li\u003e\n\u003cli\u003eTumble-polished aluminium finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFour-corner idle for precise idle control\u003c\/li\u003e\n\u003cli\u003eScrew-in air bleeds for accurate tuning\u003c\/li\u003e\n\u003cli\u003eDual accelerator pumps\u003c\/li\u003e\n\u003cli\u003eTimed spark port for vacuum advance distributors\u003c\/li\u003e\n\u003cli\u003eStreet HP base plate with ample vacuum ports for power brakes, PCV etc.\u003c\/li\u003e\n\u003cli\u003eCompatible with GM, Chrysler and Ford auto kickdown linkage (additional parts may be required)\u003c\/li\u003e\n\u003cli\u003e100% wet-flow tested by Holley before shipping\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSuits\u003c\/h3\u003e\n\u003cp\u003eBest matched to lightweight cars with a manual gearbox, or autos running a high-stall converter and low diff gearing.
