IMM Engines 408 build

Got the new cam and Melling lifters installed... I am in shock on how quite the engine runs now. I didn't realize how noisy the old lifters were until after comparisons.

As I was removing the old lifters noticed that I could not press down on the plunger inside of the lifters.... except one... it moved without problems at all.... came from the side that was tapping. Lifter might decided to bleed down much faster than the others but didn't seem right. ??

All the abnormal noisy hydraulic rollers I have seen so far did the same thing. I have had good luck swapping out only the mushy ones.
Glad it's sounding good. Definitely just a bad luck part problem. No big deal.
Now get it tuned and see how she goes.
