Alright I've got the PCM swapped and everything is running a little bit better now. I even activated the tow haul switch which will be a nice feature when driving through the mountains, the truck can be kind of a dog trying to get up the mountains and it's tough on the transmission with the larger tires. Tonight I will hopefully install the efans I am just working on putting together a wiring harness that will control them through the PCM.

As far as my thoughts on the swap go I found that the throttle response is a little bit better, shifts are a little bit smoother, and idle is a little more stable. Add to that the tow haul switch which will be very useful and I thought I would never use it and the ability to control the efans this was a great mod to do.

Now to find someone's unfinished 383 short block on the cheap...

If you want really crisp throttle response and a little more airflow, get the Jantzer ported throttle body. I had to get used to how much more responsive it was.

Sorry, a more complete link. http://www.ebay.com/itm/96-09-GM-Vo...-7L-Silverado-Sierra-Blazer-S10-/181057858515. The bbk is way overpriced and over bored so much that they give you an adapter to knock the opening back down again before entering the plenum.
