This has probably been posted a million times, but I could not find anything specific. I'm looking to get 200+hp out of my 231 v6 na- what mods should I make?
With proper cam selection, a good exhaust & keen tuning, it shouldn't be far from 200 Hp. If you're feeling adventurous, consider having some head work done. There's a lot to be gained there plus you can port match your intake to the heads as well.
There are a couple in the Comp High-Energy series. The 69-234-4 will work decently with your existing converter and rear gear assuming that you have a stock 'high ratio' rear.
If you're willing to install a mild converter and a 3.42/3.73 rear gear (highly recommended to get the most out of your car), then you'd do much better with the 69-246-4. You can see the cam specs here. Give them a call to discuss the cam further.
