ATI Balancer Bolt Length

Hi guys. I have the ATI 917470E damper and am wondering what length ARP balancer bolt you guys have used. Looking at the longer 2.20" length one or the 1.420" length. Stock pulleys. Any help is appreciated. Thanks

Is that part number for the BB or SB? I'm to lazy to go out in the shop and pull the hood off of the race car to see what part number my ATI is on my BB motor
I do stock replacement 3/4x 16x ? grade 8 bolt stock SB,BB and 426 street hemi motors balancer bolts, the stock BB are the shortest ones, maybe 2.0, maybe 1 3/4 long under the head of the bolts

2.20" long sounds like street hemi length. Thick balancer. I assume yours takes stock length.

I have that Damper and reused my short stock lenght 145-2503 ARP bolt.
One thing to check with that Damper is to make sure no bolt threads for the ring or the pulley stick thru the back side. On mine there was very little clearance between the back of the Damper and the timing cover seal area.
