what is the rpm a truck will turn stock. just reving it up. i was told they will pull to about 2300rpm stock then start lossing some power.
i am think has washers in the gsk but not sure. if it does i am going to put the 3 or 4 k kit in it.
i am just trying 5to figure out if it has been done already

 

you wont be able to tell just by reving it. if you floor it under load and it falls on its face after around 2300 to 2500 then youll know

 

mine stock would rev to 3k in neutral or park with my foot to the floor. if you have an EGT gauge flat foot it in drive from about 14-1500 rmp and watch the temp. it will start falling off in temp when the truck starts de-fueling.shoule be between 21-2300 rpm or so

 

mine keeps on getting hotter maybe he guy i got it from didnt tell me about putting springs in i guess ill know this weekend when i pull the pump out.

 

Mine starts to lose power about 2700 or so if i am just sitting reving it will rev to about 3600 thats what has me wondering. i am thinking it has been washered but not positive.

 

its hard to tell whats been done to your truck until you get in there and see/more like fix whatever theyve done

 

be careful going above 3100 rpms, could possibly float the valves!

 

yea i know the Guy that did the majority of the work on my truck really well. he said he dose not remember everything that he did to it.

 

if u dont have the springs u can rev it in neutral and it will stop at 3k and stay there

 

mine will rev to about 3600
