I heard this today from a customer and it reminded me of another quote I heard a while back.
Today:
"I used to work on cars for a living. How can a lifter go bad make the cam go bad? I just need to replace the lifter and it'll be fine."
This was about a Jeep V8 that wiped out a lifter and the engine had quite a miss to it. Pulled the rocker cover and the rocker arm moved about .010" at idle. He pulled the intake at home and came back with the lifter. It was totally concave in as much as 3/16" of metal was gone. Tried to explain that there was metal/metal contact and the cam was hurt. Lots of metalflake in the oil. He installed a new lifter and same results. No lift at rocker arm=round lobe.
A while back:
"Jerry has a 700 built by Art Carr that has a special clutch built in. When the engine makes too much horsepower, it freewheels and lets the engine rev free."
This was about a 700 behind a monster big block in a 55 Chevy 210. The guy keeps breaking the overrun clutch hub on the forward sprag and the Kolene treated ones don't fair any better.
