273 to 383 Formula S Barracuda

Would the Borgeson box work with the 67 big block K? Does the formula S package make the 273 an HP?
I like the 383 idea but understand the dilemma.
If it was a 2 barrel 273 I would go 360 or 383 for sure.
The Formula S 4 speed would have a Commando 273. Very cool cars and your headaches will melt away. Any 273 runs well, just like any SBM, just add a cam and valve springs.
