Twin Turbo 318 or Twin Turbo 225?

I've got a 65 Dart GT that was originally a 225 /6 4-speed car. I turbocharged the /6 (build pictures on my profile) and was sort of happy with the results. Horsepower was low 200's. I have a 318 block machined .03 over and a forged crank machined .01 under. Ive got a pair of 360 heads with 3 angle valve jobs. I've got the complete bearing set and new forged H-beam rods.
Out of the blue, I had seconds thoughts. I love the sound of easy horsepower with a twin turbo V8, but I love the sound of utter badassness of a twin turbo /6 monster. Any opinions would be appreciated. If I decide to go with the /6, I'm definitely selling my 318 package. If anyone is interested, please let me know. I already have about $2,000 into the V8, but I would obviously let it go for less.
Hey guys new to this forum but what ended up happening with the slant 6 if you did it what were the results?
