Whats your break in process? Last motor I had to break in was a 350 for the (1989) 1-ton chevy van (family hauler), think I ran it at 2000 RPM for 20 min and that was it. Never did this for a motor with this much money in it (relative term), one set up for this level of performance (another...

Question for the trans pros: Do I need to have the kick-down connected and adjusted for a car that will only run 1/4-1/8 mile at a time (no street duty)? I saw a post a while back that said a 727 can be destroyed if it's run without the kick-down set up right, I don't remember what the OP was...

Building a motor for my Coronet and installing a roller cam and rockers. This is a first for me, never broke in a roller cam, if there is a break in process. I wouldn't think there is, other than normal break in for the rest of the motor (rings)? But like I said this is a first for me. So...
