360's,gears And Tires

im in the process of building a 360...nothing exotic,NON stroker 360

360,.040,stock crank/rods,11:1,@.550 solid,J-heads and a M-1....im wondering if my gearing will be TOO much for the 360??...right now the duster has 28x11.5 QTP's and 4:56's

i DO need new tires and IF its too much gear,i can go 29"??
