Joined Jan 15, 2004 Messages 3,726 The 291 is better than the 484 because the 484 has water jackets that come too close to the each other and in turn crack toward them and then down the head bolt holes. Here is a discussion and a measurement between the two blocks: 4.1 casting numbers - Page 2 - TurboBuicks.com
