Hey all, I'm getting ready to make my order on a MKIV and am still struggling with engine choice. I have watched the Factory Five Engine Options video enough times that I'm certain I've skewed their youtube stats. It's excellent but I still have questions and am seeking your expert opinions and advice. I'm on the fence over a BluePrint 306 (possibly 347), with EFI versus a Gen III Coyote, most likely sourced from Forte or something similar. I can afford either option, but savings is still a minor factor. I don't mind the looks. I am a novice, I do intend to go to the build school, but that is a more important factor for me. Here are my real questions:

1. Ease of build? I am under the impression that installing the BluePrints would be simpler (smaller size, less complexity in the wiring, etc.), but what I don't know is how much simpler than a Coyote is it? A lot, a little, or is it negligible, or actually easier?

2. With the Coyote, it sounds like it's either necessary or highly recommended to do power steering, is that a fair assumption? How about with the BluePrints? Same question for hydraulic clutch.

3. Ease of maintenance. The tradoff it seems is a well installed Coyote is nigh indestructible, while the BluePrints would require additional care due to their older design (acknowledging their warranty and overall quality, I know they watch this site. I guess my biggest question is which is the better trade-off? Easier to install BluePrint or easier to maintain Coyote? What are your thoughts, or please correct my impressions if I'm wrong.

4. On the 306 versus 347, other than cost and horsepower, are there other major differences I should be aware of? It sounds like the 427s can be a bear to maintain/drive, what are your thoughts on the 347? Is it not much different than the 306, somewhere in between?

5. I guess while I'm asking: Folks seem to think the IRS option is worth it, in a similar vein to the above, how much more difficult is installing IRS than the 3 link? Is that then general suggestion?
