    Sbc 427 ?

    I'm building a 427 for my open wheel mod first ? I want to run a stewart water pump is there a lot of difference between stage 2 and stage 3 also should I run 1:1 pulleys or 20% reduction thanks for the info

    Just spend the extra for stage 3. Pulleys depend on how many RPM. Per stewart Race applications require a maximum water pump speed of 7000 RPM.
