I have a 383 in my 87 d-100 short box.I have replaced the following Dist, coil ignition module complete tune up etc.About the truck. Brought it from storage [sitting ]for 2 years. Carb was a mess ,cleaned the carb and put a carb kit in.My problem is that this truck should snap you neck right off the line but it just boggs first.It has a 727 tranny with shift kit and a very low speed rear end.It has a 600cfm carb a cam and punched out 0.60 over.Would a bigger carb do the trick maybe a 750 cfm????
