Larry,
The primaries (header tubes) are 2" OD which I guess makes them 1-7/8's. The exhaust pipe from the headers to the four glass packs is about 2-1/4" OD so I guess you would call it 2-1/8".
Thanks,
Art

Hi Art,

2511 runs a .030 over Cleveland, Performer, Holley 670, a dropped Moroso cleaner that makes the air work to get down the carb throat, and the big Ansa GTS headers/mufflers. My cam is very mild compared to yours, but my chassis dyno had HP climbing to 292 at about 6150 until it dropped off like a rock.

What size is that Big Bore choking your exhaust down to? Primaries?

Sounds like air flow issues - intake/exhaust/both?
