Serpentine Kit for Big Block 402 72 C20

[gm4x4chris]

i have done a few budget serpentine systems on big blocks with air in the past the best cost efficent way to do it is to go get a serp. set up off a early 90s b.b.c. truck from a pic and pull junk yard you may have to run a water pump that coincides with with the brakets but with a little clean up it makes for a nice acurate fit.
