I recently changed from quad 44mm idf webers to a 650dp with rpm air gap on my 347.
Also changed from a 248@.050 to a 238@.050 solid flat cam, so my observations maybe a bit squew if.
If anybody is thinking about webers, dont think twice just go for it.
The torque is far superior and drivability is way better.
I have no regrets about changing to a four barrel as tunning and setting up is way way cheaper, but if you want torque go the webers!
