Hey gang, a friend of mine has this engine in his musicle car and has been having trouble with the valve train beginning to rattle after very few miles. It is a show car and spends 99% of it's time just driving in and out of the trailer. The damage you are about to see has happened in less than 100 miles and dyno time by vender.
Please take a look at the attached pictures and tell me what you think is happening. I don't want to give any parts names or venders names so as not to spoil the thought.
The engine's exhaust push rods are longer than the intake. Only the exhaust pushrods show damage to the bottom. Only one intake push rod shows damage to the top. Check out the wear patterns.
ETA, pics and to note that the lifter on the right is an intake, the lifter on the left is an exhaust.
This engine has 10.5 compression, aluminum heads. Hydraulic lifters. 1.60/1.55 rocker ratios.
