I have installed a 5.7L Gen-III Hemi that is stroked out to 392, with the MSD Hemi-6 ignition box and harness #88864, basically the same combination as TripleThreat, who is a member of this board. I have been trying to start it without success, and it has been back-firing and popping through the carburetor and exhaust. We even tried working with MSD and switching the ignition box, with no change.

I then started looking at part numbers on the build sheet that I received from my engine builder, and discovered that he installed a 58-tooth reluctor wheel on the crankshaft. I was told by TripleThreat and another person on Facebook that this box will not work with this reluctor wheel, that it should be a 32-tooth reluctor wheel, instead.

I have looked everywhere I can think of on the internet for official information on this, and so far I haven't had any luck. If anyone has any information or can post a link, I would appreciate it.

P.S., MSD has not been any help with this question.
