Manifold ID?

I have (what I hope) is my original 351c in my '72 fastback.  It is an H code so it would have come from Dearborn with a 2bbl carb.   somewhere in time it acquired a Holley carb (which from what I can find on the 'net is a 750cfm, number 83310-1  3394, any other ID would be appreciated).  Besides the firing order on the front of the manifold the only numbers/letters are on the back.  I could not pull off the large tube running from the brake booster to the back of the carb no matter how hard I tried and do not want to cut it until I am ready to replace it.  Here are the best pics I could get, hopefully they can ID my manifold.  I have not taken the carb off to see if it is indeed a true 4bbl manifold.  

D0AE-L is an M-code 4V intake. Date code is 1A29, January 1, 1971 so not original to your car. 

83310 is a 750cfm vacuum secondary carb. It'll work fine in your application. 

Ford stamped a partial VIN on the back of the 351C block. Typically it's on the driver side of the block, just below the cylinder head. Earlier blocks had it on the passenger side, same area. 

Thanks
