flow data 351C 4v, AFD 4V, Kasse P 51
#1
To bring some factual data to the 4V head discussion.The most informative comparison data is the "as cast" flow numbers. The as cast data for Ford 4V head is extremely close to the numbers I've seen on my friends flow bench. While flow data alone is not the only data that indicates the potential for HP production, it is a valid indicator. Enjoy the read. Chuck

Roy, Your AFDs are good parts. Your whole build is top shelf. The weight savings are very real. Chuck

They flow just fine. It is a question of ending up with a CR compatible with the cam. If you go that route I'm reasonably certain the Blue Thunder intake will work with the factory ram air. Chuck

I had my AFDs opened at the factory to get me to 10.8 with my pistons, so doing the math the open chambered ones are almost identical CR. Who sell the Blue thunder?

Dealer list. http://www.bluethunderauto.com/id3.html The PN is IM-351c-4v, not the comp or Pantera version.Shop around. It may come down to availability, they are produced in limited quantities. The BT intake is only about 1/2" taller than the stock 70-71 4V iron intake. It is very similar to the D1ZX-9425-DA (and "Shelby) intake Ford over the counter part from the muscle parts program.
