HP estimate??
 

My motor now:
Chevy Bowtie Block
502 Marine HP Heads (Fresh springs and conical valves)
Roller Rockers BB 1.7 "PRO SERIES"
Edlebrock Airgap RPM intake manifold
502/502 cam from crate motor
SRP lightweight flat tops
Dimple Rods
Holly 850 Double Pumper

Anyone want to make a HP estimate???

Longrange4u,

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

I'd guess 550 hp,Smitty

Re: HP estimate??
 

Smittys close 525-550.... I'll bet the 850 is fat, try a 800.

Re: HP estimate??
 

Dyno... you think that the 850 will be fat? You think I need to jet it down or different carb?

This was in a previous post on my 496. I am running a 750 Demon Double Pumper :D

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
