Well... since you say
spending only 2500.00
I say dig deeper and try something like this on your bored block using your reground crank. Digging deeper will make you smile big, and something this will be plenty BIG enough for you... IMO

The limit on a 400 with standard deck block (9.025") is 434 cubic inches. (bored 0.030" with 4.000" crank).
Add the items Stroke mentioned, plus the machine work, plus all the nit-pick stuff that you never budget for.
