I have a little Data and a few pics I can post here. I have some video as well, but a friend will help me edit them small enough and get them on in the next couple days. Hopefully, you can read the data. Basically, this is from the best pull. Couple things to explain. First, I did remove the air hat on the last 3 pulls. Quadrajets just hate those air hats attached above them. They are a small restriction, but the larger problem is the impeller rotating in the hat measuring air movement, disrupts the air valve/flap on a Q-jet. I have seen this happen many times with Q-jets and Thermoquads. AFB's don't seem to care possibly because the air flap is lower and is weighted. So with the hat off, Air/fuel ratio, volumetric efficiency, and air usage will not show up. On earlier runs, with the hat installed, the engine was using a maximum amount of air about 603-605 CFM. The volumetric efficiency was 96.8 @ around 3000-3200 RPM and over 90% from 3000-5100 RPM's. This engine liked to run pretty darn rich. It made the best power and was happiest in the 12.5-12.7 to 1 range. To get that at the top RPM's, it was in the 11.5-11.7 range from 3000-4100 range. More time tuning could have cleaned that up a bit. Oil pressure was high and steady. I am aware many in the forum just hate to see high oil pressure, but that's just my thing I guess. I love my 80 lb. oil pumps. I guess seeing so many bearings destroyed by low oil pressure has jaded me. I have never seen a bearing damaged by too high oil pressure!
