the 366 and 427 truck moters are unbeatable for a bus or truck

In one of my dads trucks(GMC 7500) we built a 454 with (8 to 1) smog pistons RV cam stainless valves and 600 holley.
And his outher truck(Chevy C70)
has tall deck 427 it has 7.5 to 1 pistons factory grind cam and and 600 holley. It makes just as much or more low end tourq but mabe not qite as much top end power.
Besides it has factory forged crank and four ring pistons eek
