Re: best carb for my setup?
I'd probably use a 750 DP. That engine is pretty similar to mine.

Re: best carb for my setup?
A quadrajet is a good carb, and works great for an automatic. To get more response on a stickshift car however, a double pumper tends to work best. So both of his suggestions are good. With the T56, as Apeiron mentioned, a 750DP is a good choice.

Edelbrock doesn't make a double pumper.
