I was doiing a reality check on my Q-Jet and here is a formula I found that defines the Carb CFM requirements by CID and desired RPM.
CORRECTED HERE!
| Engine CID | X Max RPM | / 3456 | CFM |
| 350 | 6,000 | 2,100,000 | 608 |
| 355 | 6,000 | 2,130,000 | 616 |
| 383 | 6,000 | 2,298,000 | 665 |
| 350 | 6,500 | 2,275,000 | 658 |
| 355 | 6,500 | 2,307,500 | 668 |
| 383 | 6,500 | 2,489,500 | 720 |
| Engine CID | X Max RPM | / 3466 | = CFM |
| 350 | 6,000 | 2,100,000 | 606 |
| 355 | 6,000 | 2,130,000 | 615 |
| 383 | 6,000 | 2,298,000 | 663 |
| 350 | 6,500 | 2,275,000 | 656 |
| 355 | 6,500 | 2,307,500 | 666 |
| 383 | 6,500 | 2,489,500 | 718 |

the divisional number is actually 3456, not 3466. You should refigure.
