Well today i pulled the intake off my 340 in the duster that a bought a few months back to change it and the carb. Got to looking at the cam and found two bad lobes and lifters. I did not build this motor, and it seemed to run well, but i drove it to Livingston, TN a couple months back ,and when i got back i noticed a little valve train noise, but wrote it off as the rockers. Well i guess that i was wrong! I am guessing that it has to big of valve springs on it, is way it done this damage. It was only on two lobes that were next to each other, with the cylinders across from each other.It is the 3rd cylinders back on both sides. I have not driven the car any since the cruis in and have only started it a few times since. I did notice some fine silver coloring in the oil on the lifter valley. So i know that i am going to have to have a cam, lifters, springs. I am wondering if i should just go on and pull the motor to inspect the bottom end or flush it out good by changing the oil good a few times? It does seem to still have good oil pressure at last run. I don't want to put new cam and matching componets in just to ruin them. I pulled all the other lifters out and they are all o.k. So let me know what ya'll think i sould do?
