All Small Six harmonic balancer

[sams68]

hi. Continuing work on my 200 with the logectomy intake. Ive now got the forged pistons from Racetec with the Toyota Supra rods and Stroked crank. Holly Super Sniper EFI-Nitrous. 1.75/1.5" valves. Roller rockers and double timing chain

I cant find a high performance harmonic balance with a belt groove. Has anyone ran a stock damper at 7000 rpm with nitrous or Turbo? Are there any suggestions/experience with a high performance damper mfrs? ATI has a small block ford Super-Damper without the pully groove, but then what to do with the belt alignment??

Try all the parts stores, Summit Racing & Rock Auto. Try Pioneer.
What length stroke did you get with the Toyota rods stroked crank?

3.188" stroke, .063" additional.

What information did you have to give RaceTec to get your pistons made?
Their custom order form asks for a lot of information some I'm sure wasn't necessary.

I would like to get a set of forged pistons made for my planned 200 build.

This is SFI rated and can be made to fit. Just need to shim water pump and alternator.

If you decide to get this HB, check to see if you can purchase it from another vendor than the one Jmustang_65 noted.
$120US to ship is a little high. I had a crossflow header shipped from Australia recently and it was only $100US.

I called and talked to one of their sales persons. They were great help to get that started. We conversed with their technical person a time or two until we were all satisfied to be on the same page. I called Total Seal to have them spec the rings, then had RT provide the rings and pins with the pistons.

Deck height, rod length/width, stroke, cylinder diameter, expected compression ratio, cylinder head chamber capacity, gasket thickness, valve clearance requirements, expected piston top configuration (flat, dome, cup). There may be others, but calling was the best route for me.

Good Luck!

250 harmonic balancer will only fit the later 7 main and US blocks.

On page 18 of ''Ideal 200'' top of small six forum, there is some Romac balancers, the 200 is 1.250'' looks like 0222 would fit, check it out.
Edit, looks like 0217 is a better fit.

 

[Jmustang_65]

250 uses a different harmonic balancer.

Member used it on a Ford 200.

 

[Jmustang_65]

Dimensions for 0222 and 0217. Only differences are highlighted. Bolt holes 3 to 4 and Nominal Overall Length 2.920 to 2.630.

 

[drag-200stang]

Good job J, the 0217 looks like it would be a better fit than the 0222.
Maybe we can get Mr. Cox to edit his post, our US engines are different.

There's a post on this forum that addresses the same issue:

AU NZ - AU 250 Harmonic Damper from BHJ - Joyce Engineering

Hello, In a conversation I had with BHJ - harmonicdampers.com, the rep mentioned that they had built at least 2 dampers for a customer in AU - Joyce Engineering. Has anyone heard of them? My googling turns up nothing. Is the AU 250 damper the same as a US 250 damper? Thanks, Perry

fordsix.com

The balancer for the EA SOHC has similar dimensions to the 0217 listed above plus it has a 5-groove V-belt pulley.
Just what one needs for a supercharger.

 

[Jmustang_65]

Here you go.

Hummmm, dedicated water, alt and a/c belts??

I believe that my amended comment is true... I hope

I did consider this when I did the blower on mine, but, I doubt that 5 ribs will be enough to drive a blower. I've got an 8 rib belt on mine and I get some belt slip above 12psi and over 3000rpm. If I clean out the belt grooves I dont get slip for a short time. I use the slip as a safety factory, (stock, old bottom end).
