Fuel pump choices?

Keep on typing & show how DUMB you are.
The flow volumes I have quoted from calculation are delivered to the carb. That is why you allow a safety factor/cushion when choosing a pump using it's advertised rating. Restrictions such as length of line, bends, fittings, filter etc are factored in when choosing the pump capacity. A Carter 4600 pump that I fitted was measured for flow, by removing the hose from the carb inlet; the system used a Mallory reg set at 6psi. It delivered 90 gph, enough to feed over 1000 hp. It lost 10 gph from it's advertised or free flow rating on this car. Pumps are rated at free flow because the pump mfr has NO IDEA what sort of lines, bends, filter etc that restrict flow, that you will be using.
G force is separate consideration. Allowing for G force requires the line pressure to be high enough to overcome the G forces. Nothing to do with pump GPH rating. A 10 gph pump that pumps at 15 psi is going to handle G force better than a 800 gph pump putting out 4 psi.
And now you are making it up as you go along. Just getting dumber. I NEVER said or recommended 58* of timing at idle. You got it WRONG in the geometry thread & now you have got it WRONG AGAIN with the statement that all rocker arms have a ratio gain. There may be some, but not all. D. Vizard has proved it with the results in his BBC book & that was only a small number of brands he tested. A test using 1.65 alum rockers was tested using different length p'rods. The object of the test was to see how much the valve lift changed by changing prod length. Advertised valve lift was 0.587". Three different prod lengths were used. Measured lift was 0.574", 0.573" & 0.558". So much for your nonsense. Not a Class Act.
