I do not know this rebuilder. Or the repair shop. The repair shop has been in business 30+ years only repairing antique cars.
They always have a wide range of autos from the 20's to the 50's being worked on.
The machine shop has been in business for over 35 - 40+ years and the repair shop has used them many times.
Turns out the repair shop sent out the motor to be "rebuilt" not 3 years ago but 13 years ago but the customer changed his mind.
Too make it a short the story did sound fishy to me and I passed.
The machine shop said they would tear the Corvette motor apart and go through it again. Without explaining what that would entail. Nor did they say whether the motor ever was installed after the rebuild.
And, the best part was this "deal" would only get us back on the road one week sooner. Jeffrey
