Hi there and may I wish you a warm welcome to TorqueCars, it is a pleasure to meet you.
You'll find us a pretty friendly bunch and I'm sure you'll start to love and enjoy the forums as much as we all do.
Feel free to get involved in our other threads, all opinions are welcome and as they say "the more the merrier"!
It sounds like a great project. Why do you need the box around the carb then? Do you mean twin turbo by 'TT'?
What about adding a supercharger, this will make pretty good power on your block?
Keep us up to date with your project as well, we like to see what people are getting up to with their cars.
