Wanted!!!


I have 2 90 degree chips for a Richards box. hard to decode actual rpm range. 180 it and buy my pro stock starter kit.
 
type in" decoding "in the search box on top right of screen and read thread and click on links there is some info on Richards chips
 
Stock box will work just fine, if you need more advance install a 2-3 degree timing key.
