Yes, I have 3 core engines and I spent a lot of time researching parts. The big money is a intake, cams, and crank. The 6.2 also uses 2 spark plugs per cylinder and 1 cop to fire both. Firing order is the same as the coyote so ignition isn't a big deal. I do believe 1k hp is easily obtainable just need $$$. I estimated about 25k to get it off the ground. BTW I have 3 core engines for sale.
