1776 w/SP & single carb?

[siromega]

Hi all, I am about to drop almost 3k on a new engine, a 1776 and had a few questions:

1- Is it better (performance wise) to goto dual carbs or a single larger carb? My builder said it is harder to work on engines with dual carbs (I will maintain the car myself), and also a bit harder to dial them in as opposed to single unit.

2- Is it possible to go to single port or would a DP setup provide more torque/power? I drive 20 miles each way daily freeway and there are a couple hills with 65MPH speed limit.

3- The 1776 is going to crank out about 80-90 horsepower (with the dual port heads and dual carbs), will I wreck my tranny should I happen to peel-out at a takeoff?

4- Lastly, how much will my mileage suffer as opposed to a stock 1600,DP,single carb like it has now (about 26mpg currently) this is not an issue with me, but am merely curious as to the difference while NOT hotrodding the engine.)

Thanks in advance all.
