There are plenty here who can help you with any math. You can do something pretty nice with that budget.....my son and I spent about that much for a 340 at near 400 HP with new Edelbrock Performer heads, new SCAT rods and KB pistons, new intake, hydraulic flat tappet cam and so forth; pretty much a complete new parts build. And a 360 would save a few bucks over the 340. You might PM Dartvader; I think he did his own engine for the first time and he is easy to write to. (And maybe Straightlinespeed and maybe BadSport too).
