went to change my timing set HELP Alright I bought a 95 yukon with a really bad knocking engine and i am swaping in a 92 tbi 350. I want to change the timing set and oil pump on the 92 for some insurance while its out. So i went to find tdc #1- put vib dampner line witht the 0 degree mark and remove dist cap to find rotor points where 7 or 4 is rather than 1 or 6!!!! HELP what to do now... after some reading i found you can put #1 in dist anywhere as long as you follow firing order from there, is this true? if so i just need to see if #1 is on the compression or exhaust stroke right? Other wise i guess i need to restab the dist. please help want to make sure i get this right before i put it in the truck...thanks-Brandon

well i have it on number 1 tdc need to figure if its compression or exhaust stroke my main concern is my dist rotor is pointing at what would be 7 or 4 according to the dist chart in my manual. from my research this is ok as long i follow the firing order from where the rotor is at #1 is this right. obviously someone has messed with this dist in the past on this engine.

ok that sounds easy enough. please deal with my newbish questions i have dealt more with ls and diesel engine than with older sbc- never owned one. so when i have #1 at tdc compression stroke i just remove the dist turn the gear till it points at #1 and restab being sure it splines with oil pump?Thanks-Brandon

Ok I checked to see if the dampner had slipped and it is dead on the mark with #1 tdc compression. knowing this for sure made me confident enough to pull and restab the dist. it now points to where #1 is in the manual and actually points toward the #1 cyl. Mosquitoes got bad and it almost kids bathtime so tomorrow i will tackle the timing set replacement. thanks guys for all the help!!! hope this all works out.-Brandon
