ProStreetMonte,

Sorry to here about your build problem:
I had some of the same problems myself, about (3) years ago, I had my engine built by a machinist I thought new what they were doing. It was a big block ford with 13.1 compression and flat tapper cam, built to perform over 600 hp. Well after the start up and took it to a recommended mechanic with a dyno to tune it. He found right off that the cam had some lopes that were wore down, and he was sure that metal was being circulating around in the engine. Well he was so right.
Upset, yea, spent a lot of money yea, over 6 thousand. So I took the engine out and took the short block back to them. They broke it down wash it, clean it put new bearings, ect. ect.
Took it back to a real engine builder. and he broke it down again, found some other problems and rebuilt it with a roller cam and some other goodies. Another 4500.00.
A, I could have went off, and probably found myself in jail.
But I have more to lose than to gain, by that behavior. Life is to short to lose it over some jerks.
