Longrange4u,
I guess I'll look for the answer to my HP question here
Have you ran it yet. I even noticed that engine came with exhaust...not a bad find by the looks of it.

Re: HP estimate??
Smittys close 525-550.... I'll bet the 850 is fat, try a 800.

Re: HP estimate??
This was in a previous post on my 496. I am running a 750 Demon Double Pumper
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.
Here is the link http://www.smokemup.com/auto_math/airflow.php
the plus 15% is for marine applications based on what I have seen in this forum
