1978 Pontiac Trans Am Quadrajet Carburetor 17058253 - Rebuilt & Upgraded

This is a 1978 high performance Pontiac Trans Am Quadrajet. This listing is for a custom built and upgraded Quadrajet for use on stock or slightly modified 403 Oldsmobile engines. We always upgrade with electric chokes for reliable starting.   Throttle plates are also refurbished with new bronze shaft bushings to eliminate vacuum leaks.   All the parts we use are made in the USA. The APT screw is accessible by removing a set screw on the air horn for fine tuning off-idle and steady cruise performance.   We include a special tool to make the adjustments. We have been building quality high performance Quadrajets since 1980.   We specialize in BOP versions because we know them so well.   Hundreds of our carbs are in use across the USA on very strong engines. We use our exclusive coatings to make the carbs look great and to prevent rusting and oxidation.   Note: if the original chromate coating is still good we just clean it. All sales are final. No refunds. If something is wrong with the carb when you get it, please let us know so we can help. The photos represent the quality of our rebuilds. Rochester Quadrajets is a wholly-owned subsidiary of TCP Industries, LLC a Texas company.
