For the 360, you'll need the driver's side engine mount for 360. Passenger side is the same. You'll need a torque converter for 360 (the 360 is externally balanced so the TC has weights added for this purpose). I'd go with the Edelbrock Performer intake. It is 50-state legal, preserves all mounting possibilities for accessories, and is great for stock cams. Also, the Edelbrock 600cfm AFB is a nice match. Going 440, you'll need a big-block tranny, or an adapter for the smallblock tranny, as well as whatever other mods that I have no idea on regarding the 440's. The 360 is essentially a bolt-in.
