Have 79 Blazer with a mild built 350 engine, th350 trans married to NP203 transfercase. The truck is sitting on 38 inch tires with 4.88 gears. I have the tranny out being rebuilt right now and I am going to do some changes before it all goes back together. One change I am thinking is the converter. The current one I have in there is a P.A.W. RV-towing converter which is suppose to be a 1200 rpm stall. Now is this to low? Is it what? Let me know what you think.
