It looks to me that you are right in the wheelhouse of what Lunati suggests for that cam. It will need the gear in a 355 and that heavy of a car. The extra lift on the exhaust will be a good thing.
Why the cast crank though? For a 3.48 stroke you can buy even 5140 steel cranks dirt cheap. It says 2800 on that cam but it's not going to want to be lugged. Spin the heck out of it. Just my opinion.
Keep good fuel in it. Also it won't have the best street manners, but have fun.
