hey guys, i have a 5.0 EFI V8 and i was wondering if its possible for me to change the timing?? i hear you can get some horsepower and fuel economy by bumping up the timing a few degrees. i ask because im not sure if i can do it. i dunno if the trucks ECU controls all that stuff or what
Yes, you can advance the timing a bit.....You'll need to pull the spout connector out of it's socket to do this...yours should be right next to the distributor...gonna want to advance it to somewhere around 14*...it will help to have a timing light.... Spout connector looks like this:
once its out of the socket, how do adjust the timing?
.....First i would locate the timing marks on your balencer & clean them off good , you can rub some chalk or something on them to make them easyer to read , hook the timing light to the # 1 plug wire , passenger side front , remove spout start motor , point light at timing pointer & read timing , to turn the distributer you need to lossen the hold down bolt , turning it clockwise will advance the timing , counter clockwise will retard the timing , after setting it tighten the hold down bolt & install spout plug ....Lew
