My engine has 183,000 miles on it and I was wondering if yal would recomend me putting nitrous on it?????

 

Had 168,000 on my 5.3 with a 100 shot cam and full bolt ons and ran fine. Had some valvetrain issues and a bad oil leak that I think took out my engine not the miles or anything. Ill find out this weekend for sure when I tear down the 5.3

 

I was wondering the same exact thing. I have a 90 gmc sierra with 154k miles and i was interested in throwing the hose to it. I dont want to go over a 75 shot at the most; however, if i do this it will be with a holley double pumper carb in place of the tbi.

 

75 shot you should be alright IMO. Have to run a plate system then.

 

i had a 89 with 289k miles on it and sprayed a 125 shot to it. the truck loved it. it has over 300k on it now. truck run mid 9s on motor and in the 8s on spray in the 1/8

 

What nitrous kit are you running?

 

used a nos plate kit. a buddy of mine has a plate i believe for the tbi trucks if you need one.

 

Ok so your running a carb on your 89 truck? I want to swap mine over to a carb, I was just wondering what all i need to do besides buying the intake, carb, hei distributor, and lockup kit for the 700r4 tranny.

 

i dont have the truck anymore. it had a tbi on it. nos makes a plate kit that goes under the factory throttle body. i wouldnt change it over to carb unless you plan on putting a cam in it and a real good intake on it while your at it

 

Thanks guy! I may just go with a supercharger if I can find a good used one for about a grand!!!
