Willy's Total Perf. Kit for GM 602 Crate Motor

This is the full package from Willy's Carbs for a 602.  

Everything you need to get the best performance from your GM crate engines. Kits are available for GM 602, GM 604, and GM CT525 engines. We’ve tried it all, so you don’t have to. We gained 30+ horsepower on the dyno with these kits. Willy’s total performance packages include carburetor, spacer, stud kit, gaskets, and spark plugs. Each carburetor is dyno tested and tuned for the GM crate engines. GM 602 carburetor has Holley metering blocks; the others have Willy’s externally adjustable metering blocks. GM CT525 carburetors are black powder coated. Ignition systems and headers are available for your application on request.
