think Indy claimed they went 306 cfm max back in the day.
the real test is what ET MPH and
weight did the car they were in run.
the Bloomer heads, which aren’t offset and are factory replacement heads have actually made around that power at the track, not just a dyno.
“Using a 2.08 valve, getting 315cfm out of eddys is common for us....Indybrock will go 320. Our Indy's can go 350cfm...”
