Re: [AMC-list] BBD Carburetors and HEI--Dist Gear

TFI is slightly different in that it uses a non-stock style coil. 
With the older can style coil, the setup looks way more 'factory' than any GM HEI.

right at the beginning of this thread, i wrote that the motorcraft
shaft is 17/32" while the prestolite and delco - both points and hei -
are 1/2", and that i used my old points delco gear on my 'new' hei.

ken ames is right about the duraspark upgrade for the motorcraft dist;
i found the info with a search for 'tfi tuneup'.
