You can use 108*, and it will work. But 114* is certainly better.

Weber carbs are street carbs adapted to race engines, not the other way around. When properly tuned and set up, they do NOT spit and snort. That kind of performance will cost you races.

The problem with reversion is that the air:fuel mixture is going up, out of the engine. When the intake valves open, the mixture has to make a 180* turn back into the engine. During that turnaround, there is a brief moment when the air is not moving at all. Some fuel will fall out of suspension, and puddle in the intake tract, and the initial cylinder fill will be lean. To make up for it, the rest of the charge will be rich. That also contributes to cylinder wash down; which is a bad thing.

All of that means poor and erratic performance. Not at all what you want in a race engine - or a street engine.

I'm not sure why you would want to intentionally build an obnoxious poor performing engine. But, it's your car, to each his own. You do You.
