All I've got is a 170, 200 & 300. I haven't had the chance to get my hands on any of the older ford I6s. I like the duraspark II system & was thinking a while back that it would be interesting to see if you could take parts from one (or both) of the later OHV (200/250, 300) distributors & make a conversion for the earlier I6s (226/254, 215/223/262)? I think someone told me that the 262 & 300 dizzys may be interchangeable? This is just a thought. This way you could use easily purchased parts. I've always liked using off the shelf parts for performance.
