Well, it's my turn to ask for suggestions..

Some more good stuff. AJ/forms, I like the "advancing one tooth" on the worn chains. lol. Yes, it's a 360. Moper, you raise a lot of doubts in my mind about the engine. I have 318 magnum and the RPM intake, along with a roller cam with fuel pump eccentric from an 89 360, and the rest of the stuff that would be needed. Hmmm..... omhamoparguy, no, the motor is not broken in yet, but of the motors I've rebuilt, never have I experienced anything like this.
