Help choose engine for my 68 Barracuda

Hi

I have a mint 68 FB with 318. I also have a '70 340 and a '77 360.

The 318 is stock.

The 340 has a set of 10.5 forged speed pro pistons .030 over
Bores are good
has spun rod bearing, so needs crank welded and rods resized.

The 360 has to be bored .040 to clean up the bores
Will need the rods resized and new pistons
I have a good crank.

I have a set of 2.02 heads ready to go on.

What would be cheapest?
What would be quicker?
99% street driven
3.23 with 3000 stall converter.

Thanks

Dave
