I was looking for one to run on bbc, but nowhere in stock. But in my case now trying to find one that is set up for a tall deck. Interested in results. My air flow maxes out at 4300rpm
They make spacers to use a short deck intake on a tall deck block, but that messes with the distributor mounting height.
My airflow maxes out at 5,300-5,350 rpm. It varies a little run to run. I only see about 10 gm/sec difference between 5,000 and 6,000 rpm. Just flat lines at 5,300ish.
I have a feeling my airflow stall is almost all intake manifold vacuum buildup. All because of that stupid air inlet elbow. The MAP sits at 97 KPA at 6,000 rpm with a near open throttle body.
On a 99 KPA baro reading.
3,500 rpm = 94.9 KPA
4,000 rpm = 93.1 KPA
4,500 rpm = 91.0 KPA
5,000 rpm = 91.0 KPA
5,500 rpm = 88.8 kPA
6,000 rpm = 88.2 KPA
