830 cfm holley
Have an old 830 double pumper that I thought I might rework and put on my 468.
pocket ported 820 heads, 2.19 / 1.88
lunati 60213 hydraulic roller 241/249 @50 .625/.625
has had choke tower taken off ( I think ) so no number on top
only body numbers are on the side P32 R5
butterfly 172, 7/64 hole in front blades
metering plates 9108
power valves both blocked
pumps are 50 front and back
this is how I got it, is it worth while trying to set it up for my engine, was told to put a 1/34 base on it to increase flow and so the secondaries come in slower as these open really fast
no power valves on the street might be hard to tune.
when the car is running,dyno the beast and tune it there. 830 is a decent size for a street car.consider using an open plenum intake for more flow
