At 10/10.5 Scr, and such an early ICA,(say 60/62*) you might, at low elevation, have a problem with too much cylinder pressure/detonation. Ima thinking it would take a careful choice of parts, and best gas, maybe better than best.
But, if it can be made to survive, yes mega-torque at low rpm, like a supercharger on a stockish small block.
