The P/N 0059 solid engine mount kit for GM G and F-Body cars  places the Small Block Chevy in exact factory location and uses our popular P/N  0051 solid lower mount combined with a laser cut block mount. Tough 3/16” laser  cut brackets and Grade 8 hardware can handle as much horsepower as you can  throw at them. Solid engine mounts improve responsiveness and help prevent  engine movement, which can help in tight packaging situations (large header  primaries, turbos, etc). Solid engine mounts work best in racing applications  and may contribute to increased Noise, Vibration and Harshness. Available in  gloss black powder coat. These engine mounts are proudly used on UMI’s G-Body  test car, 1979 Monte Carlo “Green Machine”. 100% manufactured, tested and raced  out of Philipsburg, PA – USA. Note: Heavy duty engine mounts may not work with  Oldsmobile or Pontiac engines.
