Small Block Ford Aluminum Head Flow Data

Small Block Ford Aluminum Head Flow Data

The following article is broken down into four sections, click on each to link to that section:

1 - Cast Iron Head Flow Data
2 - Aluminum Head Flow Data
3 - Cleveland Style Head Flow Data
4 - Definitions

I have tried to compile many different sources of flow bench data so one could see what they could expect from a given set of heads. As new data becomes available it will be added to the charts. To print --> set your printer for "Landscape mode" (i.e. make it print sideways on a page), this should give you all the data.

Note: all flows are given in cubic feet per minute (cfm) and taken with a port pressure differential of 28" of water.

  • What can I say? Dan's GT does it all, and more. He drives it to and from work a few days and even drives it to the track on the weekends. Best of all, it has run a best of 10.87@123 MPH. In the summer of 98 Dan split the stock block and grenaded the stock AOD tranny. He rebuilt the motor and had the tranny fixed by a local shop, but ever since the car hasn't been the same. So its going back to the place who built it the first time. After that, and with a bigger supercharger Dan expects his red rocket to go even quicker. Low tens, maybe even high nines.
