Does your local racing division require you to use a stock GM cast iron 2bbl intake? This one is the ticket. Very rare SB Chevy high rise 2 bbl. cast iron intake. It is cast # 14088674. They were used on propane powered Chevy trucks in the 1980s. This is the intake with the bigger ventures & intake runners. The carb mounts 1.5 inches higher that the more commonly used Canadian 3976313 and unless your track has specifically outlawed it, this intake is within the rules. It is the intake that rules the stock classes of dirt track racing. This is a virgin intake with no cracks, repairs or stripped threads. Ready to use. VERY HARD TO FIND.
