225 Max Performance Recipe?

Wow, thanks for all the input!! So glad I found and joined this forum.
I guess if I want more wow factor at a car show then the 6 all dressed up would be the way to go, but if HP and Torque are what I’m after then I should go v8.
340 or 360 is the next question?
I figure 450hp would be more than enough for my little A body.
It’s a no brained IMO!
360, plentiful, cheap, 20 more cubic inches than a more expensive 340, a lot of it in stroke for more torque.
