Kinda touching late here, but doing it all at once is the most recommended thing. The last thing you need here, is running a 3.4 without the pcm to support the mods. Hitting the speed limiter with the stock pulley is one thing, but hitting it with the 3.4 or smaller is just asking for trouble.
Are you in Oak Grove MO? Just wondering.
OK now, carry on.![]()
