    I am using a Crane 113901 cam (.427"/.454" - 260/272) in a 383 stroker Chevy engine build. I have a Pro-Flow 3500 kit.
    Bite-Me suggested I should look for a #3512 chip, but the cam duration at .050" is intake=206 and exhaust=218. Your chart
    says this would need the stock #3511 chip. Which one would you recommend?
    Thanks, Randy

      You go by the highest number. 218. So you use #3512 that's good for 211 to 220.

                #3516 is the one you should order.

                  They are based on intake cam duration @ .050" lift.

                  Disregard any Exhaust cam duration for choosing a chip.

                  Thank You.

                    Bite_me,

                    could you kindly tell why to choose #3516 and not #3514, which is recommed to intake 231-240 intake?

                      The chips have a +- of 10 degrees, from their posted duration. The Maximum HP is around 450-480 for the Pro-Flo system, and minimum vacuum is around 10" at idle for the #3516.

                      The Edelbrock camshaft ( #7102 ) will have a idle vacuum of around 11", and make around 420 HP.


                      The important aspect is the idle vacuum. Yes #3514 will match the camshaft. But for some reason my gut is saying that the #3516 is going to be easier to tune with....I'm seeing more, and more people getting a lower vacuum, then what they are supposed to be getting.....AKA a small vacuum leak, they can't find, or just not advancing the idle timing ( 18-22 ).

                      You could actually get both chips, and use the one that works best with out having to adjust to much on the idle side.
