Critique my planned combo

I am currently building a 75 duster for bracket racing at Firebird raceway in Idaho (2700 foot elevation) - will not be street legal. Gutted with a single racing seat. 10 point mild steel cage already installed. Approx 3000 pound race weight? Hoping to run at least well into the 11s with this combo. Let me know if this sounds realistic before I go any further - only the short block is built at this point.
