Any of your basic street pumps from Holley, Edelbrock, etc. will work fine. I use the Holley unit.

Carter, I've always stuck with what Ford liked to use. Check parts stores.
Summit sells Carter, may not be Chrome. Several to choose from. Depends on motor. I have found that the Holley Chrome will leak around the bolt ring. They tend to cut the diaphram. Not sure about Edelbrock.

for my 600cfm the manual says not to use one that is anymore than 5.5 psi, stock should be all you need.

750 is too much carburetor for a 352. You will get more performance and better throttle response from a 500-600 cfm carburetor.
