so i saw that my 2000 blazer only has 190 hp. i think that is kind of crappy what can be done to get it up to like 220 or 230 if anyone knows let me know thanks

 

Engine swap?, Hi-performance cam. To gain that kind of Hp you're talking serious coin.

 

thats fine i want it to be a sleeper ha

 

Well then you could take it to hi-performance rebuild shop and give them your requirements and see what they can do. Around here, Mary Land, it's about $3K for 305 carb'd engine.
Of course the usual CAI, PCM tune and exhaust mods could gain you some in the meantime.

 

well it might help us to know what you have...
you have got to know where you are , before you can plan a journey...
things I've done for performance
K&N CAI
Flowmaster HF Catalytic Converter
Dynomax Exhaust

planning... removal of Kinetic Fan adding 19" and 10" electrics
