got a 97 with all the stuff in my sig. but the only problem with it is when i rev it up at about 2600 to 2800 rpm it blows white smoke and pops like its back fireing. Whats my problem and how do i fix it? all input is good thanks yall

 

Did you put a governor spring kit in it yet?

 

no havnt done that yet but its on the list dont have a lot of money rite now

 

You will not get the truck to rev above 2600 with any type of authority without the governor springs.

 

but that still doesnt answer my question. do u no wuts wrong? or if i get governer springs will it go away?

 

"you know whats" Sorry that drives me nuts
I agree, gov springs, I put 4k in my 94 and it can go up 3700 no prob, My stock 95 cant rev over 2300.
Sounds like your pouring the fuel to it, but it has nowhere to go so its smoking and popping. Maybe advance your timing some too

 

i would say timing check the timing

 

WHY???.....

This is a stock pump without governor springs it will not rev past 2400-2600 without defueling and doing exactly what he has described.

jake...
Your question was answered by me.

 

They will free rev past 2600. I say its low on timing mine did the same thing before I advanced my timing to 19, now it's fine.

 

How hard is it to install the 4k gsk? do i have to take it to th eshop or can i do it? and i was thinking about taking my fule plate out and just running no plate thoughts on that plaese. and timing is that hard to change? i just dont have the money really to take it to a shop to have it done
