Confidence

Bout 15 years ago had a "professionally built" 400 that I could not get to run at a decent temp. Thought at first maybe just break in but never cooled to a normal temp, and never ran to its potential. Finally got the courage to tear it down and discovered the cam was cut 5 degrees retarded, so I bought a keyway timing chain and installed it 3 degrees advanced as per advice found here. Can't stop me now!!
