Assuming you are running an ATI balancer, this one is my favorite. But you need to buy the balancer from him so the triggers will be in the correct location. Notice no crank trigger wheel. I like that.
I sell a version that works with an ATI damper that has the magnets in the damper. FHO is the only dealer that orders the integral style.
The AR177K is the least expensive solution for the Mopar wheel size. I use the Chevy wheel on my engine since I have the Chevy bolt pattern on the damper. I make pickups for both Mopar and Chevy wheels.
I used a big block Chev one I got on Ebay for cheap......it's mounted to the motor plate and seems to work O.K. The options for a small block are really limited and this was plan B , but it worked.
