does one size (5/16 shaft) fit the 200 and 250 engine? can you adjust the timing curve and does it have vaccum advance? thx. Gary

Yes, probably, yes. The curve is supposed to be optimized for 200/250s, though. For that much $$ it better be. I trust Mike to give us a quality part, and the dyno tests have proven the curve is pretty spot-on.

They come in either the 144/early 170 size or late 170/200/250 size for the shafts.

The 144ci and early 170ci had 1/4" drives, the later 170ci, 200/250ci had 5/16" drives.

The dizzys are precurve for a common street performance build based on specs I sent them. However they can be recurved if you so desire. The springs are very easy to get to.
