A method is described for the production of a high octane, gasoline boiling range product which comprises hydrotreating a highly aromatic, dealkylated hydrocarbon feed having an initial boiling point of 300/sup 0/-750/sup 0/F, an aromatic content of at least 60 wt. pct., an API gravity of not more than 25, a hydrogen content of 8.5 to 12.5 wt. pct., contacting the hydrotreated feed in the presence of hydrogen with a monofunctional, acidic cracking catalyst comprising an aromatic-selective, large pore size crystalline aluminosilicate zeolite having cracking activity and an alpha value up to 100, at a hydrogen partial pressure of 600/sup 0/ to 850/sup 0/F, a 385/sup 0/F/sup +/ conversion of not more than 50 vol. percent, to form a hydrocracked gasoline boiling range product having an octane number (RON+0) of at least 87.
