Try Crane or do a search on Summit Racing for the Crane Adj. Vac. Adv.

I'd have the PN for you but I am back OTR and won't be to the house again until Nov.

So, the Crane part # 99607-1 for V8 dizzy's will work on a 250 six DS2 Dizzy? I did not see any for a six cyl.

That is the part and I have one for my BB6 DSII which I haven't used yet...going to rebuild another dizzy I have with it but it looks identical to the stock unit I have and I did verify with the supplier it works for my application. I believe it would work unless the dizzy for the 250 is somehow substantially different than the one for the 300.

I seem to recall the bent motor ones don't fit the six dizzy - rotation is in the opposite direction and the unit is "handed".

Just looked at pics and I think yer correct, six spins clockwise and eight spins counter.
Back to square one, there are posts here that mention an adjustable vacuum advance.
Does anyone know of a part # for a six?
