Sent them a 429 out of my 1966 Cadillac Thru my local Napa Dealer. Wanted to keep numbers matching car. Got motor back 3 months later. Noise, squeak from no oil in rocker arms. Valve train noise nice blue smoke etc etc. While under warrenty local shop cleaned rocker arms, Replaced valve guide seals, Lifters etc. Never had a offer to send motor back to them. And sound like I should be glad in did not. Just so they could take in apart and deny any claim on their part. I still have the fogging engine in my car and cannot afford to do anything about it so it sits in the garage most of the time. Ashamed to take it out due the the blue smoke. They said the rings need to seat and break in. Over 1000 miles and several years later they have still not seated. Junk to say the least. Wish I had kept the job local as well. Bill in Illinois
