Reply to "4 x Weber 48 IDF (not IDA) conversion"

Ok lets throw another wrench into the mix. I am interested in the manifold, but would like to see if anyone has used the 48 IDF, 44 IDF or the 40 IDF on a 351C? If yes, any advantages in going to the smaller chokes and can you choke the 48 IDF down or are you stuck with the 48's.

Does anyone know how they work well on the 351C? I have to assume the IDF is moderately better than the IDA because of the better low and mid range metering circuits?

Also I just noticed on the Weber online site, they are touting a 48 IDA with new/improved low end metering?

Is there still the problems relating to low pulse due to the large cleveland ports?

Dan brought an interest point earlier on this thread about advantages of a plenum carb setup vs. a direct runner setup. Has anyone seen the new Barry Grant inspired inline carb setup using a plenum? There's no cleveland setup yet, and who know if there ever will be one, but they are touting that it is oh so good and on the same level as injection and actually eliminates the idle loping (not necessarily good if you like it) on radical cammed V8's because the fuel metering mixture distribution is so good?
