340 cam in a 318

It's a 272/.455 cam, a little hotter than a factory 340 cam. So If I go back to a 2bbl, and the car is a little faster in 2bbl form than a stock 318 2bbl Duster, then that pretty much proves that you can add a cam, like a 340 cam, to a 318 2bbl and it will still add performance.

That would be a good test. There sure seems to be a lot if negativity about a 318 not being able to handle a 340 cam. No bottom end and at least a converter to make it work. Is it really that big of a pooch from say idle to 3500 rpm or is it just nobody knows how to tune a 2 barrel and distributor so the engine won't jump out from under the hood when shifting from park to drive? 340 cams sure don't sound that radical.
