Standing behind your engine...
About 4 years ago I had a 454 with a 174 B&M Blower built by a local engine builder. I paid quite a bit of money considering I brought the fully balanced short block, Heads, and Blower.
Anyway he built the engine and put it on the Dyno. He broke it in and then made 10 pulls with it. It made 670 Horsepower and 646 Ft.lbs of torque. A little better then expected with a solid flat tappet cam.
So I picked the motor up and put it in my 1968 Camaro pro street car. I drove the car around for about two weeks. Maybe 100 miles. I went out one night and I can hear the motor missing. I brought it home and found out a rocker loosened up about .050. I brought it to him and he put a gauge on it and sure enough the cam was losing a lobe. He asked me to pull it out and he would take care of it. He knew I only drove it a couple weeks. He said bring it down he would call Comp Cams and get everything exchanged and would take the motor apart and clean it. He would call me when he was done. Well he called me and gave me an estimate of about 1800.00. I was stunned. He said he had to pay one of his guys to do it and he wanted to replace some stuff. I told him not to touch it, went picked it up with my friend. I get there and the guy tells me he feels really bad I told him whatever...take care.
I know it was a long story. I just can't stand when someone doesn't stand behind their work. I did nothing to cause the cam problem. He broke it in and did the dyno pulls, I just putted around for two weeks. Anyway I never used him again for anything. I have no respect for him now.
