I found mine on ebay.
Romac elastomerics are very good (I've had one for 10 yrs) but are made in Australia. There are some local dealers that stock them. Note that undersized brand-new crank noses are so prevalent on some SCAT & Eagle stroker cranks that Romac offers a special part # for proper fit on them. An easy fit will be worse than no damper at all.
I was thinking about buying a Romac my self seem to be quite expensive. I found this balancer it look like a good one any one have any opinions on it thanks http://www.summitracing.com/pa...7/overview/make/ford

This is the replacement for the 4v.
This one will probably work ok.

I already have one but it is a D2ZX. It probably is better than anything you can buy for the engine now? It certainly has more mass than even the Romac does.
The stock 4v dampener is only safe to about 6,000 rpm. It is one of the reasons the stock CJ has a 5,800 rpm redline.
I have one here in the shop on which the outer ring has come completely off of. Fortunately the engine survived it.
I keep it around to remind me how dangerous the stock balancer on the original engine is.
The Cleveland develops engine harmonics in the 6,000 rpm range (6000 to 7000) that need the mass of the Boss dampener to smooth it out.
"Some" say that it is these harmonics that will crack the block and that the Boss dampener reduces that tendency?
The iron crank actually helps to smooth them out in combination with the heavy balancer. The steel crank is less forgiving on the stock block and is thought that it hastens the cracking?
All of these aftermarket dampeners now are generic. The Boss dampener is specific to the engine by Ford Engineering for above 6,000 rpm operation.
No one knew/knows this engine better than them.
A funny thing about this dampener is that on my engine it smooths out the idle some and when you rev the engine it has this high pitch scream like an Indy engine does?
Those balancers do not come up for sale often. If you can possibly afford it, buy it by all means, even if it needs to be sent out for a rebuild. You WILL NOT be sorry.

I've decided to go with an ATI. The Summit website lists 10 different balancers, all for the 351C. Which one is correct and what is the difference between all of them?
Different brands. Internal balance vs. external. Stock vs. "performance.
Economy vs. all out.

I'm using a Scat Powerforce+ D90006 SFI harmonic damper. This damper has both 3- and 4-bolt accessory bolt patterns, has a removable counterweight if your engine is internally balanced, and is the exact same part sold directly by others as the Powerforce+ D90006 damper. It used to be available at a substantial discount when purchased through Scat but I don't know what current pricing is.
I'm using this damper on my 383 stroker, the interim 351C from my Mach 1, and another PCNC member has it on his 600 hp 393 stroker.

Pantera Doug,
I meant to say there are 10 different ATI balancers listed, all for the 351C.

4v & Proud,
I'd by it if I could get approved for membership.

Ford sold various elestomeric balancers for the Cleveland, The wts varied from 9.6 to 12.4 lbs with them getting heavier as the advertised power of the engine went up; the heaviest was on a Boss 351 or a 351-HO and the lightest was on a 351-M in a pickup. The balancers all took a 4 bolt pulley.
I THINK they all had TDC marked in the same place even though there were two or three different timing pointers. I would definitely find TDC on your own engine with an indicator disc regardless of which balancer you buy. Note a 9" disc will work on engines in a car while 12", 14" or 18" OD discs will be more accurate but will not fit on installed engines in a Pantera, only if mounted on a stand.

-------------------
there is an opposite side pointer & correlating balancer I would assume, common is a passenger side (US) pointer the rare one is on the driver side. from a 351M / 400 in a truck IIRC
small ones
big passenger side
big driver side

Might want to consider an adjustable timing pointer, as it allows precise 0 degrees at TDC adjustability.
