I have 2. 1 modified as per the MP books and the other dead stock.
IMO, you'll not need to port match it. it should be really super close to the gasket size all ready. (Fel-Pro)
Any 4bbl. carb will fit on top except a Dominator. As far as CFM goes, 600 cfm will do it.
This intake (LD340) only takes square bore carb's like a Holley or Edelbrock/Carter AFB/AVS. But it can be modified to accept a TQ.
Also, IMO, the RPM will have an edge in MPG's and power. The swooping runners and extra height of the carb pad give it this edge. While the runners are not gasket size, I would not port match the runners to the gasket/head unless a max power search is on.
