![]() Ive been throwing ideas around on how to make an old automotive head flow better. With no way of knowing what flows better, I decided to build a janky backyard flowbench.
I got as far as the manometer. mano-001.jpg And the spark plug fitting mano-002.jpg Which is really a hollowed out spark plug jbwelded to some fittings I had laying around. mano-003.jpg I screwed up and bought the wrong fittings to connect to the house shop vac to the head, so I'll fix that the next day of the one after. I also made a device to depress the valves, with the help of a dial indicator, will do so somewhat precisely. If anyone has done this, what do you feel is the easiest way to connect the vac to the cyl head? I got a sheet of lexan that I can cut a shop vac hose sized hole in and seal to the head. Air tight of course. I am not too concerned about getting volumetric flow rates now, just percent change. Plus any attempts at quantifying cfm seems somewhat suspect. Again do chime in. Thanks Ryan |

![]() There's a thread somewhere with flow rates of various mods/porting on a 530 head floating around here somewhere.
