Crate 360 vs DIY Built

^
Assuming I don't have the resources like rusty to do much of my machining or assembly, or the lack of tools for that proper assembly, or the adequate experience with a bastardization of mopar components and their proper needed marriage, (cam needs, etc.) or for that matter....Any experience assembling a complete motor ever and the future time to do it myself....then how much of a gamble is the cheaper option of a warrantied crate motor?
