Holley Injection system is a winner
By Charles A. Pizagno
Holley 502-20S Pro-Jection Throttle Body InjectionWow ! Wow ! What a better driving machine this product made my 1973 Olds Delta 88 with a 350 engine. Should have done this before. Throttle reponse is smoother and more uniform up the power curve than with a carb.And what power increase ...ZOOM ZOOM. At idle, the engine is quieter and runs with less vibrations. Suggest getting the optional O2 sensor since it does make dialing in the electronic unit easier. No no fuel smell now when I park in my garage. Now if I see the suggested fuel mileage increase, my satisfaction level will be over the top. Great product
