My guess is the tone ring is different from the early 08 down 5.7?? Can a early 5.7 tone ring be made to work on the 6.4??
Thanks guys


Simple solution is K1 part # TR 32 It's a 4 bolt design and a 32 tooth reluctor wheel. Molnar has them also.
I believe the MSD 6 will not recognize the 6.4 64 tooth count and will not work.
