Choosing the best 5.7 engine and Transmission

Oh trust me I would love a 392! We are unfortunately talking way different budgets at that point...
Sounds like I may need to do a little more research on the Nag1 and 545 to be sure. But like you said I'll be patiently looking for deals. What deal comes up may help me make a better decision between the transmissions since neither sounds like a bad option.

There are a couple sellers who regularly sell 6.4 truck engines and parts. Short blocks and bare blocks. Even saw a couple remanned short blocks cheap. I am both cheap and broke but scraped up enough to make a bid on one and they had free shipping. Now I am just taking it slow and bidding or buying parts to assemble it.
