I haven't needed to shorten the spacer with any aftermarket crank and timing setup I've used.  For the pulleys, the bolt circle on the ATI damper is just slightly off from stock FE (I think its for a big block Chev maybe?).  Anyway, all you have to do is open up the holes in the pulley to 7/16" with a drill, and it will bolt right on.  No big deal.

Current build is getting a Pro Products 9000 series. This is a short stroke under 5.5k rpm deal so it should live fine. Call me a tight wad for using it but I bought it at an estate auction for $2.50 still in the box, shelf wear but new. A factory replacement would probably also be fine but Its SFI approved so it makes me feel better. I do think Ive heard some mention to make sure and lock tight the hardware on these or they work loose and tear things up. Had to buy the new pointer to match, $13 seemed pricey compared to the dampener  :D. It's nice they offer that and its nice quality too not to cheap and flimsy like some pointers are. Wish ATI would offer one or even better, correct the timing instead of force feeding us chevy parts adapted to work.

 I was going to use an ATI but seemed like overkill after scoring the $2.50 deal so it's waiting on the shelf for a future build. Where I messed up at that sale was a on used comp roller and lifters that sold for about the same amount.. The cam was way big really unusable for anything I needed didn't dawn on me to have it reground till it was too late.  :-[

I used a Romac.  The timing marks were spot on and I didn't need to drill out the pulley holes.  I'm very happy with it.

I believe Barry recommends Romac units in his book, if I'm remembering correctly.

I must be old school. I am running a C6AE-6316-A 428 PI damper that looks like the 427 damper except for the edge bevel and timing marks and an aluminum flywheel that was balanced with my engine.  The damper was an NOS item and there is no issues with the rubber. Damn thing must weigh 20 lbs.
