Over 44 years of racing for me and I've only bought four new carbs. One was an 850 back in 1979 for a small block, two 750 Holleys for a tunnel ram big block in the early 1980's, and a new 1250 this year. The only reason I bought it was because I traded a guy from APD an Indy tunnel ram and some cash for it. All the other carbs I bought were used and I redid them.
