The Deere engine BSFC was respectable, but class eight truck engines are now

OK, so the Deere SCORE was in the mid- to upper-0.30's.  Still better than your
average aviation piston engine (low 0.40's).  Now if we can get these other
niggling issues solved (PSRU, cooling system, ...)

Combined cycle is the answer. 0.2x BSFC!  That 1800 F rotary exhaust is ideal for
making super heated steam.
