Re: TFI ignition upgrade

Well, I would like some feedback here on this if I can get some. I unboxed my HEI "clone" cheap Dragon Fire distributor today and proceeded to check it out, gear hardness, length, cap for brass terminals and flaking electrode, etc...and found out a couple of things. First off, the gear was hardened, a drill bit wouldn't even scratch it, BUT...I had read that a factory gear wouldn't work on aftermarket distributors, but I got out the calipers, checked shaft diameters, and proceeded to remove the factory gear from my old points style distributor, and install it on the new HEI, and it fit like it was made for it! It was ever so slightly tight, took a couple of small taps to get it on, put in the new pin...PERFECT! Any ideas why this won't work? Second, I installed the dizzy in the 360 WITHOUT a gasket, after visually inspecting the length, and it appeared to seat fully into the engine, I couldn't get a small flat head screwdriver tip under it, and then I had up and down play in the shaft, somewhere in the range of 1/16 to 1/8 inch, so it was not tight against the pump, so again...I'm thinking PERFECT. Next, I moved to the cap itself, popped it off, brass terminals inside and out, and I couldn't even scratch the center electrode with a screwdriver, much less my fingernail, and the cap is RED in color, not black, so I think I'm good there also. The only thing I didn't get around to, was removing the module and checking for heat sink paste instead of dielectric grease, and running in the longer screw and grounding it externally. Once I get those 2 things checked/done, I think/HOPE I'm gonna be good on this thing, and dodged the bullet. Again, any ideas why the factory gear that fit seemingly perfect, (with the dimple on the rotor tip side) will not work? Please, if anyone has any ideas on the gear or any other thing I mentioned, or anything I forgot to mention, please, let me know! I don't want to risk hurting the engine with this thing.
