It is not what the nitrous did to the plugs,that is what detonation will do and must be avoided.

 

get your timing right. get a standard nos jet combo. get 7.5psi FLOWING set on the fuel noid regulator. then go from there... this is all saying your truck runs properly on motor.

and remember since your a carb'd set up run the right jet sizes. you should ALWAYS have a bigger fuel jet number then nitrous jet number... ive seen plenty of people put them in wrong and run lean as ****

 

Thats what mine looked before I pulled timing out of it so as everyone else has said it probably the timing (its too high) make sure to get it set before you spray it again, or it may have leaned out a bit. But make sure to check your timing and as wheatley said be sure to take a good look at your plugs and see what they look like.

 

alright thanks guys, i think the machine shop cheesy pistons arent that great too.

because this motor only has about 6k on it.
motor runs really good, just needs a lil carb tuning.
thinkin about gettin a msd box for it though.

 

Well if you do end up blowing the old motor you can always go back with a efi 5.3l

 

haha, im really wanting to go with an ls swap! trust me.

wanting to swap an 6.0 in it.

but i dont have that kinda money. lol

 

surely your joking right?

 

Get em chief

 

i dont understand what i said wrong? my blue truck had 7.5 psi flowing through the fuel jet. then i ran a 73 nitrous and a 82 fuel jet. where did i say something wrong? carb set ups dont get 50 plus psi of fuel so they run a bigger fuel jet to make up for the difference in psi.

so explain your side?

 

waiting on your response also?
