I have a 69 Roadrunner that I had a nice 440 built for. I have had nothing but problems with this and will save you all the details. I finally have the motor where it is running well, but it sounds like a diesel motor running. It runs well and has plenty of power but just doesnt sound right. The block is a 1978 motor home block with a stroker crank. It is a pretty mild motor using stock valve train. It has great oil pressure as it is 40-60 at an idle and 80+ while driving. I have looked at a few obvious things that I was told to check in that I pulled the valve covers and checked for excessive wear on the rocker arms and rocker shaft. didnt see anything there. even swapped the carb and the noise remains. Anyone have any ideas?
