Hemi engine swap..is it worth it

Looked on MSD website why does it say the msd hemi 6 only works on years up to 2008. Is that because of the vvt..if I'm not using vvt it would plug in and work I assume. Not the best information on their part
Yes, because of the VVT. Can be used if you use the older cam and crank sensors and lock the VVT. I have that very thing in a Scamp right now.
