@RustyRatRod it seems Elgin does offer a "keyed" roller timing set (SS-3104) for a '68 383, where the crank sprocket should fit. So, as long as the sprocket teeth profiles match, we might have options. Albeit, 3 instead of 9 options, but just the same. Only available as a matched set, I'll reach out to them for individual part info...
Mopar in general is but 3% of the performance market, we'll have to sell a few of these I'd think, before expecting more collaboration.
Thoughts?
