i am running a 150 shot and have 180,000 miles on mine. i started with a 50 then a 75 then a 100 then the 150, im on the factory timing too, a wideband is a good idea too

Default Agreed but if you got to.

But to answer the original post's question:
It's do-able. Do a compression test, and make sure there isn't anything catastrophically wrong that would get worse if you added the extra stress of a hit of nitrous.

Personally. With that many miles, and the rest of the use/maintenance history of the engine unknown, I wouldn't do it. That's just my personal opinion. Especially with not having an extra shortblock ready to replace if something does go wrong.
Get it tuned and compression check also I am surprised nobody told you might wanna change stock fuel pump!

Swapping the fuel pump is essential on a high miles car that you want to spray on. Thanks for mentioning that.

Regardless, get it on a dyno to make sure you're not leaning out with the 'reccomended' jetting.

I'm still running the factory pump on a 100 shot, and I actually have to use the N Jet for a 100 shot and the F Jet for a 150 shot to keep the a/f where I want it.
