Not Ranked
Like I said, I was running pig rich and no matter what combination I tried with the 37mm chokes and the f7 emulsion tubes, I could not get it to lean out. I called Inglese and they recommended f16 tubes, 1.20 holders, 65 idle jets, 175 mains and 225 airs. This set up was way too lean, plugs were white. So I went from one extreme to the other. Then I read Eljaro's thread and started experimenting with leaning out the main circut and richening up the idle circut. The main circut will effect the idle circut. I tried 1.00 holders with 60 idle jets, too lean, so I went with 1.10 holders and 65 idle jets, too rich. Then I started leaning out the main circut. Tried 170, 165, and ended up with 160 mains. Tried 155 mains and it ran like crap.
Eljaro's set up is a little different with a 427. He is using f15 tubes with a 1.00 holder, 65 idle jets, 150 mains, and a 110 air correctors. The f15 and f16 emulsion tubes are similar.
Bernie has a 289 set up for vintage racing. I don't know what cam or heads he is using, but he is running 42mm chokes. 1.00 holders, 70 idle jets, f16 tubes, 165 mains, and 100 airs. That's a lot of air and fuel running through a 289! But I think he used a dyno to set his up. He said he gained 15 more horse power using the f16 over the f15 tube.
Hope this helps.
