> I would not be happy with 600 CFM on a 351C, even with low compression.

I should have been more precise with this statement. There are
two issues with the Holley 1850 600 CFM carb. First, it's 600 CFM
which may not be a problem. 600 CFM is good to around 300 HP (gross)
before it becomes a limiting factor. 2 CFM per HP is a good rule of
thumb for a square bore Holley. The bigger problem is it is a 4160
model carb with side hung floats. 4160's were made for one reason,
to be cheaper than 4150's. If you plan on doing any tuning (and you
should), then start with a 4150 or convert the 4160 to a 4150.

That looks like one. The one I was looking at was a Super Street
model but was another $100 or so at Jegs.

I hope you mean that figuratively and not that literally :-)
