I have a 95 silverado Z71 with the 5.7 litre 350. I would like to drop a 383 in it by either rebuilding the engine in it or getting a short block and building from there. I would like to know if any of you know what problems I would run into with the ECM? I would still like to use all the OE gauges etc. Is there a stroker that uses a TBI or are they all carbureted? What special modifications would I have to do to the rest of the drive train and what would your recommendations be? I've rebuilt stock engines before but I have never done anything that needed special considerations. If anyone knows of a place that sells decent 383 short blocks that would be a great help too. I'm all ears and would like to hear any of your suggestions on packages etc.What kind of auto tranny would work best with the 383, rear end etc. I appreciate all your help!!
