so how is it done? My co-worker is talking about a primary wire that goes to the PCM that needs to be unplugged or something while it's being set?

How do you start? Timing light, and set to 0* and TDC, then what ?

 

wow that sounds easy . . .

This is a bone stock truck

 

would this work on a 90 model??? im swaping the distributer cap and rotor and was told that i needed to redo the timing......????

 

same thing works on a 90 model too

be sure to take mods into account, this didnt work well on my 454ss. i had to keep my timing at 12-14 with the advance unhooked (mods are in my sig) but for a stock engine 0 will work fine

 

oh its stock...just a K&N filter...but wat if i later upgrade...have plans for headers and full exaust and chip......

 

just bump your timing up a few degrees and see where it runs the best is what i did, some people know how to figure that stuff out but i dont

 

You don't need to touch the timing to do a cap and rotor, but you can play around with it if you wanted to try and squeak a few more degrees out and see if you pick up any power

 

hell yea i wana get some more ponys from it!!! lol
but i go up on the degrees right?

 

Yes, I'd try going up 2 degrees at a time until it pings then back it off...

 

until it pings??
ive never done this befor wat is supose to ping?
wat is TOO much timing??
