What is the diameter of a stock crank pulley?
I just want to double-check that I have the stock crank pulley on my 2000 Silvy with a 5.3. I am also about to install a smaller pulley on my Whipple and want to calculate how close (or far) I am from the max rpms for the Whipple. Yea, I could just crawl underneath and measure it the crank pulley, and I will, just not tonight . I just want to compare my measurement to what someone confirms to be the stock diameter. Does anyone know the diameter of the stock crank pulley?

L-Eater and Whitt,
Thanks for the confirmation. Doing some quick math, that means with a 3.5" pulley at 5500 rpm the Whipple is turning at 11,785 rpm, which is below the 14,000 max rating (if I have been informed correctly). Just got the pulley this morning...I want to leave work just to see the effect
