A small part of this is due to lighter ring pressure against the cylinder walls, but the majority is the TBI. With a decently tuned TBI, you never get fuel wash down the cylinder walls, you never flood out, your engine is metered fuel as it needs it and it's monitored by the O2 sensor.
And you can get a TBI harness that will let you run a 4L80E tranny for around $300. That in itself would weigh heavily on my decision. I'm converting an '85 1-ton dually to TBI for just these reasons.

Ultimate replacement for carbs. Carbs had their time, now its over. I personally can't understand the attachment that some people have to them. They're antiques! Good for looking at and saying "Oh, that's how they used to do things? Oh ho ho ho ho ho!!"
Flame suit on! LOL
