I've heard various rumors. I'm wondering I have a 87 305 carb'd. It has a Hypertech stage 2 chip on it and a k&N filter on it so far. how much HP do you guys think I have so far?

Just got it so working on mods

 

If your engine is the 305 H.O. then it has 190 horse stock. I'd say with your mods now you probably have around 200.

Looks like you started out with 165 HP. You've probably added about 5 more, minus losses from wear. It does not look like the L69 190 HP was available that year.

Wow, only 5 hp from both those mods so far? Damn. Well im about to mod the carb a little and put on a new flowmaster 40 series exhaust system. Hopefully with all this i can bring it up a little more than 170hp.

Check out the engine section of this webpage it tells you all the stock information of the motors on all the third gen camaros

with some mods, ther more you add the more you get out of the mod. example: if you added headers the hp gain will be greater for the muffler. kinda like that.

I thought 87 was the last year for the H.O. motor. Might be wrong....gonna go check.

If you want big HP increases you need a whole combination of parts. Example: Mod the carb, aluminum intake, better cam, headers and/or exhaust improvements.
