I had my 340 rebuilt a year ago and it sat in my shop. I am now ready to install it into my dart, but I noticed the rocker arms were installed incorrectly. This is something of a concern because the NAPA auto that rebuilt the motor is now out of business. I can correct the rocker arm install however, I am thinking the guy may have made other mistakes. So my question, Do I fix what I see and call it good or do I spend the money and have another rebuilder tear it down and reinstall?
