Very impressive. Custom crank, oiling system, chevy rods, super low tension rings, custom stroke, iron heads ported to flow best at over .600 lift, giant solid roller, custom valvetrain, custom 950 CFM Holley, custom cooling, etc. This is a one off engine that would cost someone who wasn't a machinist 15 to 20 grand.
This was built to win a contest on a dyno, period. It would never live on the street.
