At OEM height ... Probably the P-51 head.

Not worried, just curious. I just finished a Blue Thunder standard Ford port, and wondered what to expect.

If you did a real good job, expect 250 cfm WITHOUT a test pipe.


Lee,

The Blue Thunder BBC bolt pattern exhaust will outflow the Ford bolt pattern exhaust by about 30 cfm. A good BT with the BBC pattern will flow 280 cfm WITHOUT a test pipe,,,,and a good BT with the Ford bolt pattern will flow around 250 cfm. Remember now, that BT has a total of three different exhaust ports available with their CJ heads. 1. Ford standard location, 2. Ford 5/8" raised port, and 3. BBC bolt pattern raised port.
