i run a 770k6 on my car 1991gt it is the stock routing. its a little snug to get on but works perfect

camaroeater

77"?...don't see how that possible...do you have a water pump pulley? You sure those are stock pullies?

+1 on the 84.5. you must not be running a PS pump

Sorry for stealing the thread but what other mods need to be done besides bypassing the pump? or can your car run fine without the belt spinning the pump?

camaroeater

Yes...but you will reduce the life of the catylicconverters if youpermanently bypass the pump.
