Who's setup is this?

Was a generic deal i bought local years ago, has a custom machined hub adapter go make it all work w the boss snout setup this go round. Everything is keyed to the crankshaft.

Im using a three bolt ATI balancer. Jones Manufacturing is where I got mine. They have very nice stuff, great to deal with as well. Just give em a call.

You can try http://www.petersonfluidsys.com/ also

Something w/o ten foot long crank bolt involved would be better.

The Peterson stuff uses a std length bolt and the mandrel bolts on over it.

Fabio, change that crank bolt every year....they can and will break.

It just got a newun..

call PETERSON PUMP tell them you want a CIRCLE R mandrel. it will work perfect.

ask for Pat. He will also set you up with the right pulley ratio for the pump

there it is, you can also use the moroso pulley behind it,or right on it, plus the msd crank trigger can be installed between it,and the dampner

I also made a spacer that pilots the msd wheel on the ati,or the mandrel. fits BOSS 429, or std long crank fords.

for the guys who use both, or all 3 with a belt drive I also make a spacer for the dampner hub. this allows a std crank bolt and washer to be used, while spacing the dampner out for correct crush( preload) on lower timing gear. Rather then worry about the CAP type washer I've seen some use that goes over the end of the crank because the hub of the dampner is too short to use a flat washer, and bolt

And you still have the nut on the end to turn the engine over by hand if needed.

I need to pull the alternator spacer off. I believe I still have a bag of spacers that came with it. It's working this weekend at Door wars at MIR.

Have fun at MIR and don't forget the boxing gloves lol

Hahaha. Thanks. It's good out here. We can't slow the car down enough. 100 lbs of weight, 6 degrees of timing out and an EZ plate. On my smallest plate and still not enough. 9.92s. Did qualify a 10.01 by dropping early so I'm in. Got a guy bringing me another 100lbs of weights from the hotel in the morning.

Qualified #2 spot. 1st was a 10.004.

Congrats on the #2, give em hell

Moroso makes one as well.

It's suitable for a vacuum pump.....I wouldn't run it on a drysump pump.
