Last question, Is 750 Sea Demon to small for 496
Ok I don't need any more problems 
Is my 750 Barry Grant Sea Demon going to be to small
for my 454 stroked to a 496.
Last thing I need is a lean condition.

Even allowing +15% over these numbers you should be fine
This is based on 496 inches at 5400rpm max
Total airflow requirements:
658.75 cfm
49.49 pounds of air.
3.36 pounds of fuel
Fuel Supply requirements:
0.56 gallons per minute for 14.7 A/F ratio.
38.66 gallons per hour for 12.8 A/F ratio.
146.33 liters per hour for 12.8 A/F ratio.

the plus 15% is for marine applications based on what I have seen in this forum
