1 /5 Dakota Weiss: Had a 350 race engine bored, and rebuilt by them. Not only did it take 2 months to get it back, but I had one practice session (10 laps) and started knocking. Pulled it apart and saw the cam bearings were misaligned, the crank was totally trashed. Rods were trash. To top it all off, the piston smacked #2 exhaust valve..... Dont recommend if youre looking for performance.
