I am about done in. I have spent nearly two months trying to tune my Flathead so I can drive my 32. It runs like shit. It idles fine and when you static rev it you get a lawn mower sound. On road it feels like it falls in a hole and has no power at all. I can milk it very slowly to the point where it feels like it might need second but is not pulling hard at all. 21 stud with PM-7 and 97s. 97s rebuilt over and over with parts from Uncle Max. I have rebuilt dozens of 97s and all is no different to any other car I've built for. Synced with Uni-Syn and both pulling same air. Has a tendency to die when snapped back from high revs. 37 -41 helmet distributor rebuilt and run on vintage timing fixture machine. New Skip coil, NGK plugs, Echlin condenser, new echlin points. Fuel pressure steady at 2.5 psi but does drop slightly when it revs up (to about 1.5 psi). Confirmed fuel pump push rod is exactly right length to suit lift in thickstuns manifold (had to add length due to height difference of manifold). I have a new elec Pump but want to try and solve the issue properly. Valves are opening and closing properly and timing was set on machine. Advances as it should when revved. I have read every thread I can find on HAMB and FordBarn and still runs like shit. Before I go back to the stock manifold does anyone know what I have missed? This isn't my first flathead but I feel like it's amateur hour. Why can't I sort it?
