I've been looking at a 392 Stroker kit for my truck for a while now and as tempting as it is why shouldn't I just get the 426 or the 440. The problem is that I don't know what's involved in swapping the 5.7L for the 6.1L. Anyone have experience with both the 392 stroker and the 6.1L swap? Any advice? Does anyone make a complete, or nearly so, kit for it?
