But, I do not acutally know your combustion chamber volumes. It is nice, of course, to get the piston further out towards the edge of the cylinder. I was pausing here because Jim from Air-Cooled Ranch had mentioned that he did not think the "Torque Special" was actually a very radical cam.īut, I do NOT want to put everything back together and wish I hadn't! 050 between piston and cylinder edge, cylinders torqued down to about 20 ft/lbs with nuts and washers on each head stud corner. I think you might have a stack-up of variables all conspiring to wreck your idle. Idle quality is most affected by camshaft lobe identical lift/lack o' overlap/identical lifters, calibrated clean injectors with good seals, clean tight manifold gaskets on clean straight phenolic spacers mated to a clean straight manifold flanges, tight exhaust components, identical combustion chamber cc's/deck heights/valve seating depth, clean ignition performance, etc. At idle, any discrepancy in the engine's air pumping flow characteristics will show up soonest. As you work with your engine, make all cylinders configured identically so they will behave similarly. Look at your old intake/exhaust gaskets too, see if there is any mismatching between ports and manifolds/runners.
