If you can make your way to a Godzilla they are downright “cheap” in comparison. Brand new crate engine runs $7.6k range. I’ll bet there are all kinds of tweaks to wake that sucker up.

I helped a buddy recently rebuild an F150 coyote. I was really surprised how smooth it went. Now that I know I would consider that in a future project.

At the end of the day the easy button for all of this is an LS. Most bang for your buck outside if a SBF. It’s not a coyote but the sky is the limit there. Stock 430, can push that to 550 plus without a lot of effort.
