Yep I'm that guy that had lots of problems. Most of them were oil leaks and blow seals. Head gasket issue . Now after testing I never ran over 11 degrees timing as ams pulley is off by 6 degrees. Bearings were eat up at after 5000 miles and since I rebuilt the engine myself no leaks and 20 miles on Atlanta motor speed way beating the shit out of it , and over 38 dyno pulls .I'm having zero issues.
