It's a big block, we can put that to rest, and yes there are even bigger blocks than that, 427 is still a big block. I love the look of Webers and would sure try to stay on track to keep them. I also love the 'lumpy' idle of a 427, apparently it is difficult to have both! I'd go with the webers if forced to make a choice.

As far as advice from the Cam manufacturer, I don't have that much faith in their opinions. I've seen plenty of times they don't get it right, for whatever reason. I'd trust more the advice from those who do REPLICAS and understand REPLICAS. Their handling, their weight, their typical owner, what works and what doesn't. KC and Gessford are two examples I would trust over the manufacturer.

A cam manufacturer is not going to get the detailed feedback from a replica owner like KC or other engine builders WILL get. Therefore, the real world experience would favor a replica builder.
