Just redoing that stronger recipe in gallons and so...
For 135 gallons (typical household batch of the day) and assuming a brewhouse efficiency of 70%
618lb of malts (you probably want a slightly darker pale malt or chuck in some brown malt)
18lb of Goldings
3 hour boil
Your lowest attenuation yeast (65% aprox.) should give you at least
OG 1.122, FG 1.043, 10.4% ABV, 126 IBU
