OEM refers to General Motors in your case. Dart is an aftermarket block that is designed after the GM block. Make sure the block you have or are getting has a 4.84 bore spacing. That is the distance between each bore measured center of bore to center of bore. You can measure the edge of one bore to opposite side of the adjacent bore to measure it. Call me if you need to.. |
