What was the root cause of the failure? I'll be firing up my Hemi soon (with a lot of the same parts). Just hoping to learn from your experience. Thanks!


Well, two things, you can NEVER have a big enough oil pan with a Hemi, and we did not restrict the flow of oil to the heads. I now have restrictors in the block. Hopefully, we do not limit it too much and burn up push rods.

Burned #7 rod bearing on a pass and it all let go....
