What would it take to make 1.44 lbs-ft per cid ?

I'm not a coyote engine expert. In fact I know very little about them. But I do know they make good specific output. From the tiny bit of searching I've done, the 2020 mustang 5.0 coyote makes 1.39 ft-lb/cu in.

I find this interesting but unless anyone has anything specific to do to get there it's only bench racing.

I know for me, this stuff is out of reach right now and I'll be happy if I can just get my car running and driving. I'd be very happy with a 475ft lb 4" stroke engine.
