What are you saying?
Are you confused in thinking we are talking about 4 bolt mains? We aren't. We are talking about 4 bolt motor ear mounts on truck blocks, and that those blocks do have thicker cylinder walls....I know 1st hand and have done one at 4.040 . Im sure "full roller" meant the "lifters" on that mag 360 btw, not roller rockers. People confuse terms, especially novices.
