Well,
This project is getting much, much closer to done - taken a long time, but once I get this motor fired and tuned, then the dash can go on, can put in the front and rear windows... and...well, downhill from there. But that's the problem - I am having a hell of a time firing this 6.1 Hemi (that's been stroked and bored to a 6.4). Can anyone help me with this issue? I'll top line it, then go into detail:

Top line: I (am 99%) sure I need a Holley Terminator X tune for a 32 -2 / +2 reluctor wheel timing strategy for a Gen III Hemi 6.1....do you know where I can get one / have one on hand?

Longer Version:
Motor Details
* 2006, 6.1 hemi
* stroked and bored to 6.4 (392ci) by BES Racing
* never fired
* Current sensors: Late model crankshaft, early model cam shaft (late model cam shaft sensor on hand, also early model crankshaft sensor on hand)
* Drive by wire
* Early Hemi reluctor wheel (32 -2 / +2)
* OEM fuel injectors
* No forced induction (NO turbo/supercharger, etc.)

Have verified, multiple times, that I have the right pins / wiring running to the right places on the sensors.

Current Holley Program : Running a 36-2 ignition strategy (all that's available in the Holley unit and their downloadable set up program) with all other facts incorporated from above.

When I go to fire the motor, the Holley handheld unit, on RPM, reads Sync/Stall....and it doesn't fire. The lights on the side indicate that the crankshaft sensor is NOT happy. I am fairly sure this is because the crankshaft sensor is expecting to see 34 teeth on the reluctor wheel (with the 36-2 timing strategy), but then only sees 30.

Has anyone else had this problem? I'd call Holley, but they're not open today or tomorrow and MAN I want to fire this motor!! I am hoping and praying someone has a solution to this...little bit of an unusual set up.

Thank you all!

Aaron - good progress, unfortunately I cannot help you with your non-firing situation but I would caution you to not to push too hard. I know you want to hear it run, but it would suck to damage it in the process.
 
I’d call Holley and speak with them.

Thanks 70chall440 - much appreciated. It's a frustrating spot but I definitely don't want to damage the motor...unless someone on here has the silver bullet, I'll get back with Holley on Monday - see if we can start from the ground up and figure out where the problem is.
Hope you are well!

I will, had a few conversations with their tech line already, but I think you're right - back to the drawing board.
 
Sensors need to match reluctor wheels. Early reluctor wheel = early sensor needed. If I’m reading correctly, that is not the way you’re set up.
 
Yep, wish4Hemi, you're 100% right. I figured it out and got it fired up this weekend.

The misleading part is when you read the Holley instructions they are geared towards 2013 and later hemis but this isn't stated. There are actually two different styles of crankshaft sensors for 2013 and later hemis - Holley calls for the latest model crankshaft sensor ending AA. I tried that one and then "backtracked" to what Holley showed as the early model sensor -- I believed that was the early model one -- but I was wrong.

What I figured out (and should have guessed before) was that it needed the sensor from a pre 2013 hemi - found one at a junkyard with the pigtail attached. Third sensor was the charm. Installed it and it fired instantly. Amazing to hear it for the first time.
