Supercharger or new engine? Thoughts?

What about getting a 363 short block and using your top end and other parts to save a boat load of money?

Ford Racing Short Block

I can tell you first hand that my 383 SBC has a lot more power than all of the 350 SBC's that I've owned & that's only a 33 cubic inch increase over what I've played with in the past.

61 more cubic inches (302 vs 363) has got to be an insane jump in torque, plus you won't have any intake valve shrouding with a 4.125" bore.
