09+ Eagle and 6.4 VVT delete kit???
In my opinion, the basic problem facing Hemi engine swaps has been the computer. There are a number of solutions to the problem but all of them are either difficult, and or expensive.
Hemi Tronix has a good idea. GM computers are very hackable, companies like HP tuners have been hacking GM computers for well over a decade and have software to allow the end user to control virtually every engine parameter. Yes there are companies that have hacked the Mopar computers but the level of sophistication is not as good. For a truly custom tune you need to go to a specific tuner. (As far as I know) Thus, Hemi Tronix ideas is to use a GM computer.
Using a GM computer is a good idea except that the Crankshaft Position Sensor Ring, and Camshaft Position Sensor Ring have differing notches. Thus to get a GM computer to work on a Mopar you need to swap in compatible rings. So far so good, by swapping in the computer you can use the cheap and hackable GM computer. Downside? Well by the time you install new tone rings, buy a used computer, and buy a wiring harness from Hemi Tronix you are basically in the price ballpark of many competing systems. I BELIEVE their setup is right around 2K. Now at first glance this seems a lot cheaper than FAST, but if you want to have full control you need to buy tuning software from a source like HP tuners for $400.00. Now you're at $2400.00 still cheaper than fast but you are quickly approaching the FAST price.
Comp cams sells their VVT lockout kit for $99.00, whether that would allow you to use pre 09 cams, I'm not sure, but it would allow you to run custom ground 09 and later cams. The key benefit of running a locked out cam phaser is that you'd be able to run more duration and lift without piston to valve interference. There are clearly benefits to having the ability to vary cam timing, but it does limit the amount of lift and duration you can achieve on your camshaft.
