        I have used this product in all my blown & injected alky burning sbc engines with great success from reliability,performance and longevity.
        I have also started to use this product in a triple turbocharged alky burning tractor puller that i help work on that belongs to a friend of mine that we had some problems with other brands before. they seem to hold up better since we changed over to a pro mag 44 ignition.
