ratdude747 Posted February 8, 2022 Share Posted February 8, 2022 It's listed as being for TFI'd 4.9's, but I didn't recall seeing one on mine. What's the purpose? Use a DSII cap on a TFI dizzy? Link to comment Share on other sites More sharing options...
Gary Lewis Posted February 9, 2022 Share Posted February 9, 2022 It's listed as being for TFI'd 4.9's, but I didn't recall seeing one on mine. What's the purpose? Use a DSII cap on a TFI dizzy? I think all of Ford's distributors breakerless distributors use an adapter like this. I believe the reason for it is to keep the same distributor size, and maybe casting, but allow for a much bigger cap to move the terminals apart farther due to the high voltages involved. Here's the info on the 300 six, and the ebay advert seems to see this fits the 300. And here's the MPC illustration of a 4 and 6 cylinder dizzy.
