    The 6-71 blower came off of a GM Detroit Diesel 6 cylinder 71 series diesel engine that is 426 cu/in. The 8-71 comes off of a 8 cylinder 71 series engine that is 568 cu/in. The one that you need depends on how "built" your engine is and I cant answer that.

    Ron's right u have to know what you want to use it for and how built your engine is. Unless you plan to race it and have a pro built race motor stick with the smaller one
