Rochester Tri-power.....with Precision CNC machined Billet aluminum secondary (end carbs) small bases. These have all new shafts, correct secondary throttle plates, carb arm and heavy duty torsion return springs. All three Rochester 2G's (small base) are remanufactured with Walker kits and NOS parts, coated in high heat ceramic gloss black, and configured to function as a tri-power. Carbs are Ethanol fuel ready and ready to bolt up. I've sold many of these sets here on HAMB and never had an issue. Need a complete system? I have parts for that. Price is + actual shipping.
