Yeah maybe that's true for 292's? I'm not that familiar with the 292 version. I've just heard of people saying that they had to drill the block when switching from an inline 6 with front pan to engine with a rear pan. I don't think that's necessary on 194-230-250's. It wasn't on mine anyhow. Isn't the block for a 292 the same as the smaller 6's? I thought the only difference was the head?
