Custom built by Competition Carb, Holley and Demon carbs used on dyno only at USA Performance Engines in Denver Colorado. I just retired and so everything must go. All carbs work perfect, no leaks, no loose parts, very clean inside and out and always emptied and kept dry between use, and I can help with any tuning you need. Some of these carbs were over $3000 to build. I have a 390 cfm, (2) 650 cfm, (1) 750 cfm, (1) 800 cfm and (1) 850 cfm. ALL will pass tech anywhere. $400-850 each. Also one 800 Holley brand new never used $500. Call for more info or picture. If you are in Colorado I will come to the track and tune it for you. On average our carbs made 20-35 more HP than the carb the customer owned for their own engine.
I can supply plenty of business references before you by. CALL OR TEXT only because I dont check my ads very often.
